“There's six quarts of blood in the human body. This isn't going to be pretty.” ~Dexter to Miguel ("The Damage a Man Can Do")

Bay Harbor Butcher 18
The Bay Harbor Butcher 18 was the name given to the eighteen dismembered bodies that were found by scuba divers in Bay Harbor. After recovery, they were laid out in a field morgue to examine and identify. Investigators never discovered that they had been killed by Dexter Morgan who had dumped them from his fishing boat. Due to the location where the bodies were found and how they were cut up, the media dubbed the unknown killer the Bay Harbor Butcher. After DNA analysis, all of the victims were found to be murderers that had slipped through the law.
Kills Outside The Code
Every season (after Season Two) saw Dexter kill at least one person that didn't meet The Code of Harry, intentional or otherwise.
- Oscar Prado - Dexter stabbed Oscar with a bayonet during a struggle in the home of a drug dealer. ("Our Father")
- Nathan Marten - Nathan was a pedophile who was strangled by Dexter for taking photos of Astor. ("The Lion Sleeps Tonight")
- Camilla Figg - At her request, Dexter performed a mercy kill. ("Easy as Pie")
- Jonathan Farrow - Dexter believed that Farrow was killing models, but his assistant was the true murderer. When Dexter learned that he had made a mistake, he broke Farrow's blood slide and discarded it. ("Slack Tide")
- Rankin - Dexter impulsively beat him to death with an anchor because Rankin enraged him with verbal insults. ("My Bad")
- Stan Liddy - Dexter stabbed Liddy with a knife after Liddy kidnapped him. It's possible, though, that Liddy had killed someone in his past since he was a former police officer. ("Hop a Freighter")
- Norm - Norm was impaled with a pitchfork when he demanded money from Dexter, even though Dexter knew that the gun being held on him was not loaded. ("Nebraska")
- Alberto - When Alberto pulled a gun and began to threaten and rob Cuban immigrants, Dexter stabbed him with a harpoon. ("This is the Way the World Ends")
- Clint McKay - He was the first and only innocent victim to receive a ritualistic kill (wrapped in plastic and dumped into the ocean). ("The Dark... Whatever")
- Beth Dorsey - She planned to set off a poison gas bomb in the Miami Metro Police Department. However, Dexter trapped her in a room, and only she died. Dexter was considered a hero and no charges were filed against him. ("Talk to the Hand")
- Oliver Saxon - Dexter killed Oliver with a pen and it was recorded on a jail's camera. Since Dexter had set it up as self-defense, no charges were filed against him. ("Remember the Monsters?")
- Billy Fleeter - Dexter prepared the kill room and tranquilized Fleeter. Then Fleeter was killed by Miguel Prado with a stab to the chest. ("The Damage a Man Can Do")
- Alex Tilden - Dexter and Lumen Pierce set up the kill room together, but Tilden was killed by Lumen with a stab to the chest. ("In the Beginning")
- Jordan Chase - Dexter subdued Jordan at his camp. Then Lumen Pierce killed him with a stab to the chest. ("The Big One")
- Benjamin Caffrey - Dexter led Caffrey into an ambush aboard a ship, where he was shot to death by Isaak Sirko. ("Helter Skelter")
Below is a list of characters whose deaths Dexter either indirectly caused or could have prevented.
- Harry Morgan - After he walked in on Dexter dismembering Juan Ryness, he committed suicide. Dexter later guessed that Harry killed himself because he couldn't live with himself after seeing what Dexter was capable of doing to another human being. ("There's Something About Harry")
- Jenna Lincoln - Jenna was a murderer who was killed by Peter Thornton, a man attempting to emulate Dexter. Dexter himself had planned to kill Jenna, but Thornton kidnapped her after he discovered that Dexter wanted her dead. Following a clue left by Thornton, Dexter watched from afar as Thornton killed her. ("Dark Echo - Chapter Three")
- A Third Husband of Cindy Landon - Landon murdered her third husband on the same night that Dexter invited Cindy on a date (to lure her into a trap). She likely would have killed her husband, even if she hadn't been interested in Dexter. ("Dexter Early Cuts: Cindy Landon")
- School Yearbook Editor - He was killed by Jeremy Downs. Dexter could have prevented the editor's death as he had a chance earlier to kill Jeremy, but didn't because Jeremy claimed that the man had raped him. ("Circle of Friends")
- Jeremy Downs - Committed suicide in jail (with elements of his own modus operandi) after he told Dexter that he felt nothing and hated every minute of his life. ("Circle of Friends")
- Paul Bennett - After frequently beating up and raping Rita throughout their marriage, Paul was beaten to death in prison after being sent there for using heroin, which Dexter injected into him. ("It's Alive!")
- Eva Arenas - Was killed on the orders of Little Chino. While this murder would most likely have happened even if it hadn't been for Dexter, he could have prevented it had he killed Chino earlier, which he failed to do as Chino escaped from him. ("Waiting to Exhale")
- Unidentified man - Was shot by his elderly father who panicked because of the Bay Harbor Butcher news and thought it's him when he came out from the night shift late. Note: This incident was mentioned to have happened by Deputy-Chief Matthews, although Matthews did not confirm whether the man died of or survived his gunshot injury. ("See-Through")
- Two victims of Ken Olson - An unidentified drug-dealer and unidentified wife-beater were killed by Olson, who was inspired by the Bay Harbor Butcher vigilante spree. ("Dex, Lies, and Videotape")
- James Doakes - Was killed in an explosion by Lila West, who was trying to keep Dexter from being caught. ("The British Invasion")
- Ellen Wolf - Killed by Miguel Prado, Dexter's first apprentice, after Dexter allowed him to kill murderer Billy Fleeter. This gave Miguel the confidence to kill Ellen, who he'd wanted dead. ("About Last Night")
- Kyle Butler - Beaten to death by Arthur Mitchell while he was looking for the alias Dexter was using. ("Hello, Dexter Morgan").
- Rita Morgan - Killed by Arthur Mitchell, who wanted revenge on Dexter for causing him so much trouble and took said revenge by killing his wife. ("The Getaway")
- Trent Casey - Unwittingly led Travis Marshall to the college where he taught. ("Get Gellar")
- Tony Rush, Louis Greene, Alex Dubrozny, Andres Rodriguez, and two Colombians - All killed by Isaak Sirko in search of Viktor Baskov's killer, except for Alex, who was made to kill himself. ("Are You...?", "Buck the System", "Run" and "Swim Deep")
- Isaak Sirko - While he was bleeding to death, Dexter did nothing despite his medical education and ability to transport Sirko to a medical facility. Instead, he waited for him to die, partially fulfilling Isaak's desire to be reunited in death with his lover Viktor Baskov and partially because it was an easy solution to Dexter's problems with him. ("Helter Skelter")
- Maria LaGuerta - Maria realized that Dexter was a serial killer and when she later saw his sister Debra pointing a gun at him, she told Debra to kill him. However, a very emotional Debra killed Maria instead. ("Surprise, Motherfucker!")
- Shaun Decker - A murderer who was beaten to death by Zach Hamilton, who Dexter had taught the code. ("Are We There Yet?")
- Max Clayton - Dexter is responsible for his death because instead of killing Oliver Saxon after kidnapping him, he left him to be arrested by the police. When Max saw Saxon had been tied up, Saxon pretended to be a helpless victim and tricked Max into releasing him, before stabbing him in the heart, killing him. Elway even points out that Dexter is partly responsible. ("Monkey in a Box")
- Debra Morgan - Was shot by Oliver Saxon moments after Clayton's death. She later went to the hospital, and although she was in good condition at first, an undetected blood clot deprived her brain of oxygen and eventually stopped her breathing. She was placed on life support, and Dexter and Quinn were informed that she was unlikely to ever recover from her vegetative state. After killing Saxon, Dexter came back and shut Debra's life support off, killing her. Despite the fact that she is a direct kill, she is also considered indirect, for if Dexter had killed Saxon earlier, Debra never would have been shot and thus never would have suffered the injury that caused her to suffer brain death, and forced Dexter to mercifully kill her. ("Remember the Monsters?")
- Possible Storm Casualties - In the series finale, Dexter caused a flight to be delayed while trying to get Jacob Elway off of Hannah's trail. The flight was further delayed because a hurricane was too close for the plane to take off. The casualties of the hurricane are unconfirmed, but there is a chance some of the people who were supposed to be on the flight out of Miami were killed.
Below are characters killed by Dexter in his illusions, imagination, and dreams.
- Lipsey - He was beaten to death in a dream ("The Dark Defender").
- Welsh - He was beaten to death in a dream ("The Dark Defender").
- Santos Jimenez - He appeared in Dexter's dreams twice, being killed both times. In the first dream, as his younger self, his neck was snapped by Dexter ("The Dark Defender") and then, later, he was actually killed by Dexter. In the second dream, he appeared as a dismembered corpse (but cut up differently than in real life since his head was still attached) ("Resistance Is Futile"). Jimenez was the only one of Laura Moser's Killers to be killed after Dexter dreamed of it.
- Juan Ryness- He was stabbed in the chest in a dream ("Easy as Pie") but he had already been killed ("There's Something About Harry").
- Brian Moser - Dexter ran a car into his illusion ("Nebraska") but he had already been killed ("Born Free").
- Post office worker - Her throat was slashed in Dexter's imagination ("Buck the System").
- Vince Masuka - His throat was punctured with a pen in Dexter's imagination ("Buck the System").
- Unnamed future kill - He was stabbed in the chest in his imagination ("Do You See What I See?").
- Valerie Castillo - She appeared in a dream as a victim, although she was already a corpse. In the dream, she came back to life (ironically, the opposite of being killed) ("Return to Sender").
Dexter was a suspect in deaths that he did not commit.
- Rita Morgan - Because the modus operandi did not exactly match The Trinity Killer's, Detective Joey Quinn started to suspect Dexter.
- Dexter Morgan - In the series finale, Dexter was believed to have committed suicide by sending his boat into Hurricane Laura. In fact, he survived and only faked his death.
Witnesses To His Kills
Although the first rule of the code was, "Don't get caught," several people witnessed, or almost witnessed, Dexter killing someone.
- Brian Moser - It's not known how many people Brian saw Dexter kill but, likely, more than one since he spent many years tracking him and was able to replicate the set up of Dexter's kill rooms.
- James Doakes - He was present when Dexter killed Esteban and Teo Famosa. However, Doakes only saw Dexter go into the cabin when he snapped Esteban's neck, and Doakes was in front of Teo Famosa when Dexter shot and killed him. Still, Doakes knew that both were killed by Dexter. Prior to that, Dexter had killed Jose Garza with Doakes only a few feet away. A plastic sheet was up to block Doakes' view of the kill but he was fully aware of what was going on.
- Lumen Pierce - She saw Dexter kill three people: Boyd Fowler, Dan Mendell, and Cole Harmon.
- Several Immigrants - They witnessed Dexter kill Alberto, although none of them could speak English well, and were unlikely to turn Dexter in since Alberto was threatening all of them.
- Several Shooters - They were present when Dexter killed Oleg Mickic at an outdoor shooting range, although none of them were aware that he killed him.
- Evelyn Vogel and Debra Morgan - They saw Dexter stab A.J. Yates through a mattress with a curtain holder.
- Joey Quinn and Angel Batista - They watched video footage of Dexter kill Oliver Saxon.
- Debra Morgan - She witnessed more of Dexter's kills than anybody, with the possible exception of Brian Moser. She saw him kill Beth Dorsey, Travis Marshall, Andrew Briggs, and A.J. Yates.
- Harry Morgan and Debra Morgan - They walked in on Dexter's kill rooms unexpectedly. Harry walked in as Dexter dismembered Juan Ryness, and Debra walked in just in time to see Travis Marshall be killed. (Maria LaGuerta also entered a kill room, but this was part of Dexter's plan, and she was tranquilized moments later.)
Deaths He Witnessed
- Laura Moser, Miguel and two unnamed victims - Killed by a group of three led by Santos Jimenez, while Dexter and Brian, little kids at the time, watched and were greatly traumatized.
- Carl - Executed via electric chair, while Dexter watched from the audience, brought by Harry Morgan.
- Jenna Lincoln - Killed by Peter Thornton, while Dexter watched from afar.
- Billy Fleeter - Killed by Miguel Prado under Dexter's supervision.
- Earl Doorman - Beaten to death by Trinity while Dexter watched on a security room monitor.
- Alex Tilden - Killed by Lumen Pierce under Dexter's supervision.
- Jordan Chase - Killed by Lumen Pierce under Dexter's supervision.
- Erin Baer - Died when her neck was punctured when a trap Travis had set up was sprung.
- Wayne Randall - Leaped into the road so that he could be hit by a truck. Notably, Dexter was also the last person Wayne talked to, and he ended up being covered in his blood.
- Sal Price - Died of a heart attack induced by Hannah McKay while Dexter watched.
- Benjamin Caffrey - Killed by Isaak Sirko while Dexter watched.
- Isaak Sirko - Died of a fatal wound from George Novikov as Dexter watched.
- Maria LaGuerta - Killed by Debra Morgan while Dexter watched.
- Evelyn Vogel - Killed by Oliver Saxon as Dexter watched.
PRIOR TO SERIES ATTEMPTS
- Josh - A boy who bullied Dexter when he was a teenager. Harry intervened before Dexter could kill him, and warned him that there were consequences for everything he did. ("Shrink Wrap")
- Jenna Lincoln - Dexter arrived at her house to kill her, only to discover a note, which lead him to an address, where he witnessed Peter Thornton killing her.
- Tony Rodriguez - Dexter arrived at his house, only to find that the resident of the house was now 'Julian Belows.' Dexter then stated "His kind rarely leave forwarding addresses."
- Sam Duke - Shortly after picking him to be his next target, Doakes walked in with him, having arrested him earlier.
DURING THE SERIES ATTEMPTS
- Jeremy Downs - Dexter attempted to kill him, but then decided not to after Jeremy told him that he had only killed the man because he was raped by him. ("Popping Cherry") Dexter later discovered that Jeremy committed another murder and decided to go after him again. This time, however, the police arrived and arrested Jeremy before Dexter could kill him. Later, while in custody, Jeremy kills himself in a fashion similar to how he killed his victims. ("Circle of Friends")
- Jimmy Sensio - Dexter suffered from performance anxiety and decided to let him go, only because he was blind. He later flees town. Dexter took a blood slide from him, though, he later cleaned it when he didn't kill Jimmy. (It's Alive!)
- Robert Brunner - Dexter was going to kill him, until he discovered he was wearing an ankle brace, and therefore not one of the men responsible for hurting Lumen. ("First Blood")
- Joey Quinn - Dexter intended to kill him because he believed he was the one who was keeping him under surveillance. However, when he goes to where he believes Quinn is, he is instead greeted by Stan Liddy, who had actually been the one watching him all along. ("Hop a Freighter")
- Brother Sam - Dexter stalks him to his house, where he supposedly shoots and kills Nick. Dexter then follows Sam to his garage, where he intends to use the M99 on him. However, Sam is alerted of Dexter's presence by the dog, Eli, and takes Dexter into the garage, revealing that Nick is alive ("Once Upon a Time").
- Leo Hernandez - Dexter tracked him to his house, and waited for him to come out so he could kill him. However, Mike Anderson and other cops showed up, and a shootout ensued that ended in Leo's death. ("Just Let Go")
- Jonah Mitchell - Confronted him in a hardware store and attempted to kill him. However, after Jonah reveals that Rebecca Mitchell killed herself because of their mother's obsession with their father, and that he killed her because of this, Dexter decides to spare him, despite Jonah begging to be killed. ("Nebraska")
- Louis Greene - After Dexter injected him, he started seeing black, and later talked to Deb about what he was feeling, with Louis in the trunk. After Deb left, he took Louis out and left him on a bench. ("Sunshine and Frosty Swirl")
- Hannah McKay - Dexter had her tied down on the kill table, but after she told to do what he had to do, he cut her free. He ended up having sex with her on the very table she was almost killed on. ("Do the Wrong Thing")
- Isaak Sirko - Dexter went to Viktor's apartment, where Isaak was staying, to kill him, but instead found the Unnamed Hitman, who he killed in self-defense. ("Argentina") Later, when Isaak came to Dexter's apartment for help, Dexter pinned him to the wall with a knife to his throat, but didn't kill him because Jurg Yeliashkevych was holding Hannah hostage. ("Helter Skelter")
- Benjamin Caffrey - Caffrey was given to Dexter as a target by Isaak Sirko, who Caffrey and his partner Oleg Mickic, were sent to kill. He was later killed by Isaak himself, with Dexter's assistance.
- Joe Jensen - Dexter attempted to kill him, but found he couldn't, because he had promised Debra not to take a case from the police. He then cut Joe free, knocked him out, and left him for Miami Metro Homicide. ("The Dark...Whatever")
- Maria LaGuerta - Dexter planned to set up her death to make it look like she and Estrada had shot each other. However, Debra arrived and LaGuerta, waking up after being tranquilized, tried to convince Debra to shoot Dexter. Dexter then told Debra, "You're a good person" and "Do what you gotta do." In the end, Debra shot LaGuerta in the chest, killing her. ("Surprise, Motherfucker!")
- Lyle Sussman - Dexter believed him to be The Brain Surgeon, and went to his cabin with the intent of finding proof that he was a killer. There, he found several tools, thus proving Sussman's guilt, at least in Dexter's mind. Immediately after finding the tools, Dexter heard a creek in the back of the building, so he went to investigate and found Sussman hanging on a hook. He later discovered that Sussman had been coerced to murder Leonard Welks by The Brain Surgeon, and was immediately killed afterwards.
- Miles Castner - Hannah asked Dexter to kill Miles, but since he didn't fit the code he didn't do it. However, when Dexter came to Miles and Hannah's boat, he was armed with a knife, so he may have expected a confrontation to occur and was ready to defend himself if the need arose. Also, when he heard Hannah and Miles struggling, he took the knife out, implying that he was ready to kill Castner and likely would have if Hannah had not killed him first.
- Zach Hamilton - Although Dexter initially planned to kill Zach, after discovering that he killed Norma and attempted to kill his father simply out of care for his mother, Dexter realized how similar he and Zach were, so he cut him loose.
It took more than one attempt for Dexter to kill these targets.
- Little Chino - (took 3 attempts) Dexter accidentally woke him up when cutting his cheek, and he managed to escape. Dexter tried to kill him again, this time with a tranquilizer gun, but he knew he was coming for him, so, Dexter was attacked by his gang members. Dexter does manage to kill him later on.
- Santos Jimenez - (took 2 attempts) Dexter brutally beat him in the bar Santos Jimenez works at, he attempted to kill him with a knife from the bar until Lila calls him and talks him out of it (she thought she was talking him out of using drugs). Dexter leaves him there and goes back to the hotel he and Lila stayed in. Later when Dexter was walking out of the bowling alley where he bowls with Batista, and Masuka, Santos Jimenez attempted to kill him, but ran away when Lila yelled for help. Dexter follows him to his secret cabin in the everglades, and he kills him with a chainsaw.
- Fred Bowman - (took 2 attempts) Dexter went to his house to kill Freebo, but found him fighting a man named Oscar Prado. Dexter's appearance surprises both men long enough for Freebo to break free and he manages to escape the home as Prado turns his attention to Dexter. Dexter ends up killing Prado in self-defense and flees the scene, leaving Prado's body in the home. Dexter tracks Freebo to Teegan's home, chokes him unconscious and takes him to the house's garage, where he sets him vertically up on a picnic table in plastic wrap. Dexter stabs him in the neck with the same knife that Oscar Prado had attacked Freebo with the day before.
- Benny Gomez - (took 2 attempts) Dexter was ready for the kill and had a perfect ambush near the bar which Gomez frequented, but being sleep-deprived he fell asleep for some time and woke up to a policeman suspecting him of being a possible drunk driver. Gomez was able to flee at the same time. Dexter later succeed in injecting Gomez with M99 in the trailer park where Benny lived.
- Jonathan Farrow - (took 2 attempts) Again, as in case with Gomez, Dexter was ready for the kill but just when he was trying to get Farrow out of the club he noticed that Quinn was also there and preferred not to risk. He killed Farrow next night, instead.
- Arthur Mitchell - (took 7 attempts) Dexter was ready to inject Mitchell with M99, but was suddenly shocked of him being a family man and decided to wait with the kill. Later Dexter traveled with Arthur to Tampa, planning to kill him there, but when he set the kill room and tried to subdue Mitchell in his room in the hotel, he failed to find him. After hours of searching Dexter's third attempt at his life was when Arthur attempted suicide, and Dexter grabbed him to keep him from falling. Then, realizing he would technically still be dying by his hand, Dexter began to loosen his grip, but before Arthur could fall, several people helped Dexter pull him up. Several episodes later, at thanksgiving, Dexter pulls Arthur off of Jonah, and throws him in the kitchen, grabbing a knife as they fall down. Arthur's wife and daughter come in, and get to Arthur, all looking in fear at Dexter. Dexter leaves the residence, angry. Dexter attempts to kill him once again, using the M99 to knock him out (which he also once failed in the apartment of Kyle Butler, that being attempt number five) and then places him in the van. But Dexter is arrested for hit and run shortly after, leaving Arthur in the van. Never the less, Dexter was able to, finally, kill him.
- Boyd Fowler - (took 2 attempts) Dexter injected him, but before he could take him to the kill room, Boyd shot him with tranquilizer. Later on, Dexter does manage to kill him.
- Travis Marshall - (took 3 attempts) Dexter wraps a cord around his neck when he gets in his car, and tells him to drive to the arranged kill site. However, on the drive, Travis reveals that he was too weak to do any of the killings, and Professor Gellar had to do them all. Dexter lets Travis go, hoping he will eventually lead him to Gellar, and then drops his car off at his house. Later, after it is revealed Travis was behind all the murders, Dexter attempts to tranquilize Travis on the docks, but after suffering from dizziness brought on by Wormwood, Travis knocks him to the ground and uses Dexter's own needle on him. Dexter later manages to kill him, anyway.
- Ray Speltzer - (took 2 attempts) Dexter decides it's time to take down Speltzer, first examining his RV (which had been impounded but was released following the confession being thrown out) to turn it into a suitable (and portable) kill room then finding his trophies. However, what he did not expect to find was Speltzer returning to his camper early. Before Dexter could react Speltzer tackled him, overpowering him rather quickly between throwing him about the camper (even into the ceiling) and using his pure strength to triumph over Dexter's jiu-jitsu. Dexter even catches him in a hold (by his arm) but Speltzer's pure determination allows him to break free and subsequently knock Dexter out in the process. Later, Dexter awakes in an abandoned building, built like a maze similar to what Speltzer made for his own victims. Dexter manages to escape the maze and his second attempt won becuase it was purely unexpected by Speltzer.
- Hector Estrada - (took 2 attempts) Dexter was about to kill Estrada, but just as he was about to, Estrada asked Dexter if he was in on it with "that bitch cop". Estrada went on to reveal that Maria LaGuerta pushed for his parole, causing Dexter to realize that Maria had set him up. Dexter then took down the picture of his three year old self, and took Estrada from the room, leaving the plastic and the still running chainsaw. Dexter got away from the scene, the conscious Estrada in tow, threatening to kill him if he made a sound. However, Estrada managed to break away from Dexter, and then jumped into the water, escaping from his would-be-killer. The next episode sees Dexter catching Estrada again, and using him to lure Maria LaGuerta to the scene. After LaGuerta is knocked unconscious, Dexter shoots Estrada in his stab wound, intending to shoot LaGuerta next so it looks like they killed each other. However, Debra was the one who ended up shooting her.
- A.J. Yates - (took 3 attempts) After discovering his "lair", Dexter later returned with the intentions of killing Yates. However, he found that he had already left, and also found and saved one of his victims, Janet Thornton. Later, Dexter tried to lure him into a trap by telling him his father was dying, but after Yates arrived and Dexter revealed himself, telling Yates he "depended on him to play the role of the good son," Yates pulls his father's oxygen in an attempt to kill him and call nursing home personnel. AJ then jumped out of a nearby window, while Dexter had to hide behind the door from the personnel. Later Yates was trying to kill Evelyn Vogel in her apartment when Dexter deduced where he was.
- Oliver Saxon - (took 4 attempts) After discovering he was The Brain Surgeon, Dexter and Evelyn Vogel lured him to a cafe, Dexter allowing Vogel to believe she would be able to speak to him again. However, Dexter drugged her, and went to the cafe alone, where he watched Saxon and waited for him to come out. When he finally did, Dexter followed him, but discovered that his tires had been slashed. Later on, Dexter and Vogel devised a plan so that Dexter could capture him and kill him. Dexter believed Vogel would meet him in a public place, but instead she chose to meet him in private, at her home. In the end, this was her undoing, and Saxon killed her as Dexter watched, escaping afterward as Dexter held her in her dying moments. In the second to last episode, Saxon comes to Dexter's apartment with the intentions of killing him. When he tries to stab the supposedly sleeping Dexter, he grabs his hand and Debra puts a gun to the back of his head. He is then tranquilized, and taken to a kill room, his own "operating room". They talk, and during their discussion, Dexter realizes he doesn't need to kill Saxon, but he still needs to die - so he calls Deb. After she arrives, he tells her to arrest Oliver. However, after Dexter drives off, Max Clayton arrives and undoes the restraints keeping him down. Immediately after, Saxon grabs one of the nearby knives and stabs him. Just as Debra walks in, he takes Clayton's gun and shoots her but, as he is escaping, Debra shoots him in the arm.
In each season, Dexter killed someone important or personal to him, usually with a method that deviated from his normal modus operandi.
- Brian Moser, his brother, whom he killed by slashing his throat and hanging him upside down, causing Moser to die from exsanguination. On a side note, this was the method that Moser used to kill his victims. ("Born Free")
- Lila West, his lover whom he had left, and whom he killed by administering a spinal epidural (to ensure her death would be painless), and stabbing her in the chest. ("The British Invasion")
- Miguel Prado, his 'best' friend with whom he bonded with over killing, and whom he killed by strangulation with a wire, to emulate the modus operandi of The Skinner.("I Had a Dream")
- Arthur Mitchell, initially his friend and fellow serial killer, then the murderer of Dexter’s wife, whom he kills with a hammer whilst playing his favorite song. On a side note, the hammer was part of Mitchell’s sequenced killings.("The Getaway")
- Jordan Chase, the founder of the Group aka the Barrel Girl Gang (of men who raped and tortured Lumen Pierce), was killed actually by Lumen, with Dexter’s assistance, using his usual modus operandi. However, the killing deviates slightly from Dexter’s method at the time, as Chase is completely clothed, and belted to the table.("The Big One")
- Travis Marshall, a fellow serial killer who tried to help Dexter find Professor Gellar, whom he had actually killed years prior by stabbing. ("This is the Way the World Ends")
- Maria LaGuerta was to be killed by gunshot, in order to frame her for cross-killing with Hector Estrada before being interrupted by Debra, who shot Maria instead. ("Surprise, Motherfucker!")
- Oliver Saxon was killed in view of a camera with a pen to the carotid artery. However, Dexter managed to make it look like self defense and avoided being incarcerated. On a side note, this is the only kill to be witnessed by both Angel Batista and Joey Quinn. ("Remember the Monsters?")
- Phil Bosso - Initially, Dexter believed him to be the Phantom Arsonist, so he stalked him to see if he could find any evidence. Instead, he found proof that Bosso couldn't be responsible for the killings, since the weekend they happened he was at a civil war reenactment. ("The Dark... Whatever")
- Ed Hamilton - After Norma Rivera's death, Miami Metro began to look for suspects in her murder. One of the suspects was Hamilton, a man that she worked for. It turns out that Norma was Ed's mistress, so he fell under the radar of both the PD and Dexter. However, before leaving Ed's residence, Dexter ran into Zach Hamilton, who told him that his father was "an asshole, but no killer." This led Dexter to discover that it was Zach who killed Norma, not Ed. ("This Little Piggy")
- Carlos Guerrero - Ready for his next hit, Matt Chambers, Dexter was suddenly interrupted before the sedating act by Debra's phone call. She invited him to celebrate her new job in Homicide. In the restaurant, Dexter noticed Guerrero and even followed him in to the bathroom. Dexter considered whether it was necessary and safe to use his equipment and kill room to kill Guerrero, and then kill Chambers at a later time. He eventually decided against it, concluding that Guerrero himself chose "to live in the dangerous world."("Crocodile").
- Ricky - Struggling to remain calm, Dexter was aggressive towards him to the point that Ricky noticed and joked about the shovel as a potential murder weapon. Dexter clearly had that same thought for a few seconds. ("Popping Cherry")
- Rita's Neighbor - Dexter said to himself that he can easily "help" Rita with the neighbor and her dog. It's possible that he was not thinking of killing the dog exclusively (as he closed his eyes for a second to relax and found another solution). ("Popping Cherry")
- Lucas - Despite watching Downs all along in trying to kill Lucas, Dexter had no plan to rescue him; therefore, leaving Lucas in great danger. But Dexter was, eventually, far more benevolent than usual and saved him. ("Popping Cherry")
- Suspects - Jose Molina, Pedro Famosa, Manuel Valdes, Ramon Fernandez - were suspects in the El Coyote case, so were for some time endangered to become victims until Dexter picked up Jorge Castillo as a prime suspect ("Love American Style")
- Neil Perry - Dexter had planned to kill the Ice Truck Killer so when Perry falsely confessed and tried to make himself look like The ITK, he put himself in danger. However, though he was on Dexter's radar, there wasn't much of a window between the department finding Perry's planted evidence and his arrest, so it's unlikely Dexter would've even had the chance to kill him. ("Circle of Friends")
- Allison Sera - Her life was dependent on whether Dexter killed Roger Hicks or chose not to. Considering his problems with the Bay Harbor Butcher Investigation, Sera was lucky that Dexter did kill Hicks. ("An Inconvenient Lie")
- John Henry - Attempted victim by Ken Olson, who was inspired by Dexter's deeds. ("Dex, Lies and Videotape")
- James Doakes - Dexter implied to him that he could "unleash the beast at anytime." However, Doakes told him that he would "hate himself for the rest of his life" if he did so.
- Astor and Cody Bennett - Attempted victims by Lila West, who captured them using M99 acquired from Dexter's bag (general motive was also connected to killing Dexter). ("The British Invasion")
- Various Profiles - Damon Clarkson, Anthony Cowley, Harold Cranes, Dustin Devereaux, Cole Dunning, Michael Donner, Thayer Drake, Kevin Eisland, Mario Espinoza, Corey Estherhouse, George Evans, Abraham Forrester, Vincent Fraser, Bradley Garrison, Michael Grant, Josue Guerrero, Glenn Kobayashi, Shawn Petersen, Frederick Sellers, Keith Stalker, Curtis Yoritor (?), Alan Yonnken (?), Alex Zeller (?), Ilk Zellew (?) - When Miguel Prado wanted to share a kill, Dexter browsed through their profiles, choosing a particularly difficult victim, Clemson Galt, but Dexter ended up killing him in private. Later, Miguel and he shared the kill of Billy Fleeter. (Note: Profiles on Guerrero, Kobayashi, Petersen, Sellers, Stalker and were shown, while other names only appeared in the list near them on the left of Florida Criminal Records Database). ("Sì Se Puede")
- Albert Chung - Shortly before suggesting Ellen Wolf, Miguel talked about the Chung case, proposing that he and Dexter "take care" of the problem themselves. In response, Dexter said, "I guess it can't hurt to keep tabs on Chung, if the police can't bring him in on their own." However, Miguel clarified that he saw Chung as merely a "symptom," while Wolf was the "problem" he was referring to. ("Easy as Pie")
- Andy Brightman - When Dexter broke into the Brightman residence to warn Andy against vandalizing any other properties, the two briefly fought after he vaguely threatened to kill him (decapitate, specifically). During the ensuing struggle, Dexter's threats became more serious and, at one point, he put his hands around Andy's neck. ("Blinded by the Light")
- Jesse Brightman - To blackmail Andy out of vandalism, Dexter not only suggested Andy's own decapitation, but also threatened to do it with his son, which mostly was a bluff. ("Blinded by the Light")
- Kyle Butler - Was in danger of being killed by Trinity, but Dexter prevented this. ("Hello, Dexter Morgan")
- Elliott Larson - When Dexter was picking up his things to move into Debra's apartment after the death of Rita, Elliot came in to ask whether his help is needed. Dexter dropped the kitchen knives and, feeling annoyed, paused with his hand (and knife) a few inches from unsuspecting Elliot's chest, clearly thinking and trying to suppress the urge for murder, partially caused by grief over his loss. ("Hello Bandit")
- Barry Kurt - Dexter, believing Astor and her friend Olivia had been kidnapped, pulled him out of the back of a patrol car and demanded to know where they were, threatening to kill him. He later finds out that Barry abuses Olivia so Dexter beats him into leaving her mother and says "If you ever come back, believe me, I wont go easy on you next time," implying that he will kill him. ("Teenage Wasteland")
- A Suspect - While Dexter tried to get a DNA swab, a suspect was being uncooperative, and Dexter grabbed him by the neck. Although it is doubtful he was going to kill the man, the gesture is still very hostile, especially considering that Dexter imagined killing someone incidentally at least two times that very day. ("Buck the System")
- A Truck Driver - While driving away from the grocery store, where he had talked to his sister for the first time in months, Dexter was cut off by a man driving a truck. Dexter proceeded to get in front of the man and both of them pulled over. He then got out of his car, and went to the man, angrily putting his hands around his neck and slamming him into his seat. However, he saw a young boy in the backseat, so he went back to his car and drove off. ("A Beautiful Day")
- Evelyn Vogel - Threatened to kill her, but was most likely bluffing, as pointed out by Vogel herself. ("A Beautiful Day")
Suggested by Others
- Tony Tucci - He was tied up by the Ice Truck Killer for Dexter to kill and Tony even begged him to do it, but Dexter didn't because Tony didn't fit code. ("Let's Give the Boy a Hand")
- Debra Morgan - She was tied up by the Ice Truck Killer for Dexter to kill, but Dexter saved her because he was "fond" of her. Later, for comic relief, Dexter chants to himself, "I will not kill my sister," when Debra annoys him by her habits, living in his apartment. ("Born Free" and "Waiting to Exhale")
- Ellen Wolf - Suggested to Dexter multiple times by Miguel Prado, Prado later killed her himself, using the confidence he gained from Dexter.("Easy as Pie")
- Unknown Person - Miguel had a candidate for their next shared kill the next day, after killing Billy Fleeter and Ellen Wolf but the idea was abandoned by both of them. ("*The Damage a Man Can Do")
- Jonah Mitchell - He begged Dexter to kill him. ("Nebraska")
- Ramon Prado - Suggested by Dark Passenger, Harry Morgan. ("Do You Take Dexter Morgan?")
- Lumen Pierce - Suggested by Dark Passenger, Harry Morgan. ("Practically Perfect")
- Laci - Suggested by Dark Passenger, Brian Moser .("Nebraska")
As many psychopaths do, Dexter started his killing spree with animals. Through the years, his self-control towards animals improved. By age 20, he was killing humans.
- Buddy - He was a dog who belonged to the Billups, neighbors of the Morgans. Dexter killed it because Doris Morgan (who was sick) wasn't able to sleep due to its barking. ("Dexter") It may that Buddy was the same dog that chased Dexter and caused him to fall on spikes and badly injure himself. If so, then it was also personal vengeance. ("Father Knows Best")
- Unknown Animals - While having a conversation with young Dexter about Buddy, Harry mentioned that there were a lot of other bones buried in Buddy's grave so, by then, Dexter had killed several animals. ("Dexter") Dexter continued to secretly kill animals in his teenage years. Harry uncovered this after finding Dexter's knives with blood on them. ("Dexter")
- Pheasants - Before a hunting trip, Harry told Dexter what type of gun he should use to kill pheasants. At the last minute, Harry decided to kill a deer instead, but they likely hunted pheasants at other times. ("Popping Cherry")
- Deer - One was shot by Harry and finished by Dexter, who stabbed the animal after Harry gave him a knife. ("Popping Cherry") They presumably went on to hunt deer at other times. In Season Four, a deer was accidentally hit by Arthur Mitchell, and then finished by Dexter with an axe ("Slack Tide").
- Hunting - It's implied that Dexter was really into hunting in his teenage years. It was a way chosen by Harry to channel Dexter's urge to kill. It's likely that Dexter killed dozens of different animals legally as a hunter. Although Dexter became a skilled marksman, he avoided using guns as an adult.
- Stone Crabs - While on a date with Rita during the Crab Festival, it was suggested that Dexter ate at least one, but only Rita was viewed smashing a crab claw with a mallet. The seller fresh cooks the crabs. ("Dexter"). (In Dexter: The Game, he smashed dozens.)
- Mosquito - One is shown in every opening since "Crocodile." It is crushed by Dexter, leaving a drop of blood.
OTHER ANIMAL INTERACTIONS
- Banjo - He was a puppy, owned by young Debra. Even though Dexter didn't view it as a target, Harry got rid of it to eliminate even the possibility of it being killed. ("Are You...?")
- Jaworski's Dog - When Dexter broke into Jamie Jaworski's house, it ran toward him. But Dexter notably avoided injury to it by quickly closing a door (in contrast to the animal-killing flashbacks in the same episode). ("Dexter")
- Walter - He was a mistreated beagle who belonged to Rita's neighbor. The dog was enclosed in her backyard and ignored. It's barking was annoying to the point of sleepless nights and nervous breakdown for Rita and her kids. Dexter thought that killing it would be an easy solution, but decided it would be "wrong." ("Let's Give the Boy a Hand")
- Alligators - During his stalking of Jeremy Downs, Dexter was startled by a gator, causing him to stumble, and express his anger. ("Popping Cherry"). James Doakes had a near miss with an alligator when he escaped the cabin in the Everglades In the same episode ("Left Turn Ahead"), Dexter mentioned that he and Doakes had fed the Famosa brothers to alligators. In "Slack Tide," the arm of a murder victim was found inside an alligator.
- Bob the Goldfish - After Dexter helped Cody flush his dead goldfish down the toilet, it resurfaced. This foreshadowed the incident when one of his victims was retrieved by the Ice Truck Killer from Bay Harbor. ("Return to Sender").
- Armadillo - Dexter used a broom to sweep it out of Rita's house. ("The Dark Defender").
- Police Dog - As Dexter walked past a parked police car, a K-9 inside started to bark furiously at him. Dexter stopped walking and glared at the dog. ("Our Father")
- Eli - He was a guard dog owned by Brother Sam. When he started to bark at Dexter, Eli was nearly injected with M99. ("Once Upon a Time")
The following are victims that held a special meaning to Dexter, or caused a special event to unfold. Most of these victims didn't have a blood slide taken, some due to lack of time, and others due to Dexter's personal choice.
- Mary - Mary was a woman who thought she was helping those that were sick by overdosing her patients with morphine, killing them. Harry pointed her out to Dexter, who took action and ended up wrapping her entire house in plastic, readying her for a kill. This one was a bit messy in the end but certainly the most meaningful. Dexter stabs her multiple times in the side of the torso until she is dead.
- Juan Ryness - Juan is a pimp who beat one of his prostitutes to death, for unknown reasons. Being one of Harry Morgan's sought after targets, Dexter thought the best way to make his father and his dark passenger happy would be to kill Juan. So he tracked him down and Harry caught him in the act of dismembering his body in plastic, which both made the demon inside of Harry satisfied, and sickened the man holding it, who ended up committing suicide shortly thereafter, as he couldn't live with himself after seeing what Dexter was capable of doing to another human being, and realizing what he had created.
- Alex Timmons- Alex is a former sniper for the Marines who was discharged and then, for unknown reasons, then killed four random, innocent people by sniping them. He was presumably arrested on suspicion of doing so and then released, which would explain how he came into Dexter's sight as a potential victim. Dexter kills him with a single stab to the chest with an USMC combat knife, a reference to Alex's being in the marines and collects his very first blood slide for his collection. In the Early Cuts series, Alex had murdered three children, though this was not canon in the Showtimes series-in the Showtimes series, none of his victims were children, apart from a seventeen-year old girl.
- Brian Moser - Brian is Dexter Morgan's older brother and strangely enough, shares somewhat of a "family trait" where he murders people in a similar fashion to his brother (except with surgical, precise cuts). Brian was present at their mother's death and unfortunately ended up in an Psychiatric hospital until he was 21 years old, where he was then released and took on the alias Rudy Cooper off of a man he had killed. Brian would continue killing until he finally desired to get his brother's attention, finding out that the two of them were exactly the same. Thus, Brian started setting up clues to help Dexter recall who he was and eventually the two met face to face (as brothers), with a bad ending that leaves Debra Morgan in a tragic state and Brian dead, made to look like a suicide. Dexter intended to kill Brian while he was still asleep, so that he wouldn't know what was going to hit him. He woke up however and the two shared an emotional conversation, before Dexter slit his brother's throat with a knife and left him to bleed out just like his victims. Dexter does not take a blood slide from his brother, claiming he wasn't a trophy, but needed to be put down for the protection of his sister.
- Santos Jimenez - Santos is one of Laura Moser's Killers, specifically the man responsible for sawing her into pieces along with several other people in a shipping container. This incident would forever warp Dexter and Brian's life, turning them into serial killers, with Dexter eventually finding Santos, working in a bar in Naples. When the two finally met, Dexter played into finding out more about Santos until finally attacking him viciously and nearly killing him, until deciding not to at the last moment. This would create a problem, as Santos followed Dexter and ended up trying to kill him, which failed and only prompted Dexter to follow him to an abandoned cabin, where Santos was sawed into pieces just like he had done to Dexter's mother long ago. Dexter does collect a blood slide from Santos, but according to the kill list his blood slide was "lost".
- Lila West - Lila is a fiery woman that introduces herself to Dexter at an NA meeting that he attends after he pretends to be addicted to heroin (to divert suspicion from Rita after he framed Paul Bennett). An outgoing woman with a British accent, it's later revealed that Lila has a bad addiction to fire (arsonist). Soon she causes a terrible breakup between Rita and Dexter and it leads to Dexter and Lila being in a relationship. Dexter listens to her advice and tries to control his urges (though she thinks his urge is to shoot heroin). Before long, she becomes obsessed with Dexter and ends up using Batista. Dexter makes the choice to kill Lila after his multiple attempts to get her to back off fail, her murder of James Doakes, and her threats to the lives of his children. Dexter follows Lila to Paris, stabs her in the heart with a blade, and rests her body in a plastic garment bag which he zips closed. He first insures that she doesn't feel any pain with a spinal epidural. Dexter doesn't take a blood slide from her.
- Miguel Prado - Miguel was Dexter's first "accomplice". He is also the brother of one of Dexter's victims (Oscar Prado). He was killed by Dexter after he killed Ellen Wolf for threatening his career as an A.D.A (claiming she put the guilty back on the streets and deserved to die) and targeted Maria LaGuerta. Dexter kills Miguel with a metal wire, wrapped around his neck, eventually breaking his neck. Dexter doesn't take a blood slide from him. He does however remove several patches of skin off Miguel's shoulder, only to frame George Washington King for killing him.
- George King - Dexter originally planned to kill George King, however, he was forced to do so when King held him captive. Interestingly enough, King is the only one of Dexter's victims to have him tied down, and on the verge of killing him. However, Dexter escapes, breaking his hand in the process and kills King by breaking his neck and throwing his body onto an incoming police cruiser, staging it as a suicide. Dexter does not take a blood slide from him, only because he did not have enough time to do so.
- Arthur Mitchell - Arthur Mitchell was a successful serial killer that was active for 30 years, as well as a family man. With a kill count of over 120 people, he was one of the most prolific serial killers that Dexter killed. Dexter takes a blood slide from him, making him the 12th confirmed blood slide in the second box. He was the only main antagonist killed by Dexter to have a blood slide taken, and placed in the slide box.
- Boyd Fowler
- Dan Mendell
- Cole Harmon - Boyd, Dan, and Cole were members of The Group aka the Barrel Girl Gang. Dexter takes a blood slide from Boyd, but not Dan. He does take a blood slide from Cole, but gives it to Lumen. His reason for targeting them is they are members of The Group. The other two members, Alex Tilden and Jordan Chase, are killed by Lumen.
- Travis Marshall - Travis was a serial killer who had hallucinations of Professor James Gellar. Although it is initially believed that Professor Gellar is the one behind the killings, it is eventually revealed that Gellar was killed before the events of the season, which meant that Travis was behind all of it. Travis then accuses Dexter of killing Gellar, and believes him to be "the false prophet". He later tries to use Dexter for one of the Doomsday Tableaus, "The Lake of Fire". Then he tries to use Dexter's son, Harrison Morgan, as The Lamb. However, Dexter stops him, and then kills him in the very church Travis used as a hideout. Just as Dexter stabs him, Debra Morgan walks in, causing Dexter to utter "Oh God". Dexter has to explain to Debra what happened and convince her not to call the police. Afterward, she goes to get gasoline from a gas station, and they proceed to burn Travis' body. Dexter did take a blood slide from Travis, but it was broken and left at the scene of the crime, where Maria LaGuerta discovered it.
- Viktor Baskov - Viktor was a prominent member of the Koshka Brotherhood and the leader of their operations in the United States. Viktor was brought to his position by the Brotherhood's leader, Isaak Sirko who was Viktor's lover. During a feud with the Colombian Rojas Cartel, the Koshka Brotherhood's rivals in Miami, Viktor was sent there in order to hold off the Colombians, which his subordinate, George Novikov, failed to do independently. During his time in Miami, Viktor murdered a stripper named Kaja Soroka, and attempted to flee the country. While doing so, he encountered Detective Mike Anderson, who discovered Kaja's corpse in Viktor's trunk, prompting Viktor to shoot him dead. Later, Viktor was tracked down to the airport by Dexter, who injected him with M99 in the bathroom before taking him to a makeshift kill room and bludgeoning him to death with a fire extinguisher, avenging Anderson's death.
- Ray Speltzer - Ray was a serial killer who would trap his victims in a maze like area, and would then chase them, eventually catching them and beating them to death. At his last victims maze, he attempted to kill Debra Morgan. This caused Dexter to make an attempt on his life, but he was knocked out and taken to a maze of his own. After a short chase, Dexter escaped from the building. Later, at the cemetery, Dexter knocked Speltzer out with a shovel, hitting him so hard that the shovel broke. When Ray awoke, he was strapped down on a table before the cremation furnace. After a short conversation, Dexter killed Ray with a stab to the chest, using the broken shovel. Dexter did not take a blood slide from Ray; in fact, Dexter placed his second Blood Slide Box on his chest and burned it with Ray's body.
- Hector Estrada - Hector was a notorious drug lord of Miami's past, often mentioned by name (as simply "Estrada") throughout the series as the crime lord who ordered the death of Laura Moser, but never seen until the last two episodes of Season Seven. For the majority of the series' continuity, Hector was in prison, until he was released by Maria LaGuerta, who was using him as bait to catch Dexter Morgan, who she believed was the Bay Harbor Butcher. When Hector was free again, Dexter took the opportunity to try to kill him and brought him to the same shipyard where Hector's subordinates killed Laura Moser in front of her two sons. Before Dexter could kill Hector with a chainsaw, LaGuerta and two detectives arrived at the shipyard, forcing Dexter to free Hector and make his escape. Hector wouldn't be free for long, as Dexter managed to find him again and brought him back to the shipyard and made him call LaGuerta (who believed he was dead) to have her come to the shipyard as well, where Dexter would kill them both and make it look like they killed each other. After the call, Dexter and Hector discussed how Hector ordered Laura's death only because if he didn't, he would have gone to prison, and he was making a choice between him or her, which strongly mirrored Dexter's decision to kill LaGuerta. He then proceeded to stab Hector in the chest, finishing him off.
Disposal of Bodies
- Prior to Series - Until Dexter purchased his fishing boat, Slice of Life, he 0ften dumped bodies out in the Everglades. After be bought the boat, Dexter usually dumped his victims into Bay Harbor. Divers later found many of these remains ("It's Alive").
- Season One - Dexter dumped Valerie Castillo without dismembering her for lack of time ("Love American Style"). Brian Moser would later dive into the ocean and return Valerie's corpse to where she was killed, so she likely received a proper burial/cremation ("Return to Sender"). Brian Moser's body was left for the police to find, with his death made to look like a suicide ("Born Free").
- Season Two - Dexter changed his dumping spot from Bay Harbor to the Gulf Stream because it would carry bodies to a greater distance. After Dexter killed Esteban and Teo Famosa at the cabin, he fed their bodies to alligators ("Left Turn Ahead"). What happened to Lila West's body is unknown. It was last seen zipped up in a garment bag, so it was presumably disposed of whole ("The British Invasion").
- Season Three - Miguel Prado was left out in the open, made to look like a victim of The Skinner ("Do You Take Dexter Morgan?").
- Season Four - The only season where all of Dexter's kills were dismembered and disposed of into the Gulf Stream. This includes Arthur Mitchell, the main antagonist ("The Getaway").
- Season Five - Jordan Chase was dismembered and disposed of normally by Dexter, after Lumen Pierce killed him ("The Big One").
- Season Six - At the beginning of "Nebraska," Dexter is seen dumping bags containing Nick's body parts into the Gulf. Alberto, was thrown into the ocean from a refugee boat after Dexter stabbed him with a harpoon ("This is the Way the World Ends"). Debra walked in on Dexter killing Travis Marshall, so he was not dismembered or disposed of properly. Instead, with Debra's help, Dexter burned Travis' body and made his death look like a ritualistic suicide ("This is the Way the World Ends").
- Season Seven - Viktor Baskov was wrapped in a garbage bag and dumped whole ("Are You ...?"), while Ray Speltzer was cremated ("Run"). Oleg Mickic ("Helter Skelter") and the unnamed hit man ("Argentina") were left where they were killed. Clint McKay was thrown overboard immediately after he was killed. ("The Dark... Whatever"). Dexter initially planned to dismember Hector Estrada to mirror what happened to his mother. But after discovering that LaGuerta had set Estrada free so Dexter would kill him and she could prove that he was the Bay Harbor Butcher, Dexter decided to kill both of them and set it up so it looked like they shot each other ("Surprise, Motherfucker!"). Isaak Sirko was shot by George Novikov and later died on Dexter's boat after being brought to where Viktor Baskov was disposed of. Isaak was presumably dumped whole afterward ("Helter Skelter").
- Season Eight - Andrew Briggs was left in his motel room, eventually being bagged by the coroner ("A Beautiful Day"). Ron Galuzzo's disposal was not shown, so he could have been dismembered ("What's Eating Dexter Morgan?"). A.J. Yates was dumped like Baskov, covered by a trash bag and in one piece. Dexter helped Hannah dispose of Miles Castner. Saxon was killed at Miami Metro, in self defense, with Joey Quinn and Angel Batista as witnesses, so his body was presumably taken to the morgue. Debra's body was dumped into the ocean, partially wrapped in a white sheet ("Remember the Monsters?").
- Killed by Others - Three of the eight whole bodies that Dexter dumped into the Gulf Stream were killed by other people. Isaak Sirko died of a bullet wound he received from George Novikov. Miles Castner was stabbed in the throat by Hannah McKay. Zach Hamilton had his brain sawed out by Oliver Saxon.
- Witnesses - Four of his disposals were witnessed by other people. Brian Moser witnessed Dexter throw Jorge and Valerie Castillo overboard (although Brian was not seen at this time). Lumen Pierce helped Dexter throw Cole Harmon's remains overboard. Dexter also helped Lumen dispose of Jordan Chase. Several immigrants witnessed Dexter kill Alberto and throw him into the ocean. Evelyn Vogel and Debra Morgan were present on his boat when Dexter dumped of A.J. Yates.

Victim Count Analysis
- Accuracy of Order - Dexter's Kill List, unfortunately, cannot be placed in an accurate order, as many of the victims were identified during the Bay Harbor Butcher Investigation by FBI Agent Frank Lundy's Task Force. Although there are no unaccounted for victims, there are three unexplained names - Orozco, Smith, and Fowls. Fowls was a name seen on the slideshow Frank Lundy presented.
- Unreadable Names - There are a few unreadable names presented during the Bay Harbor Butcher case, although they go over the total amount of victims Dexter had by that point. It is unlikely that they were dumped before the blood slides, since all victims on the list were identified via blood slides. The writers likely forgot to include victims Dexter had killed during the first season.
- Kill Count Between Seasons - At one point, Dexter mentions that he has to satisfy his urge to kill at least once every month. Between seasons, there are time skips in which slides taken from unknown victims appear in Dexter's box. Between the end of Season Two and the start of Season Three, the second box gained 4 unknown slides, which implies a four-month period. Between Season Three and Season Four, 12 unknown slides were placed into the box which implies a twelve-month period. Another 13 unknown slides were placed in the box between Season Five and Season Six, which implies a thirteen-month period. Since it was specifically stated that six months had passed between Season Seven and Season Eight, it is likely that at least 6 additional kills were committed during this time.
- No Blood Taken - Dexter started taking blood slides when he killed Alex Timmons, so there are unaccounted for victims before that point. Also, Dexter did not take blood slides from a number of his other victims, including his brother and people that he killed on the spot, such as Dan Mendell. Counting all of his known victims, Dexter did not take blood from, at least, 39 of them.
- Additional Victims - During Alex Timmons' Early Cuts episode, Dexter states that he has "killed dozens of bad guys," which implies that there are at least twenty-four victims before Alex's death. Seven of these are accounted for: Mary, Juan, an unnamed victim, an unnamed drug dealer, Robert Milson, Peter Thornton, and the unidentified victim that Dexter was stalking prior to spotting Alex. This leaves at least 18 unaccounted for victims, thus bringing the total of his kills to 153.
- Season One and Two - According to Darkly Dreaming Dexter, with the addition of Father Donovan, the total blood slide count was 37. However, in the TV series, the number is 40, because the blood slides added up to a total of 46 by the end of Season Two and Dexter had only kept six additional blood slides (Jaworski, Chambers, Jorge Castillo, Meridian, Little Chino, and Hicks).
- Season Four - In "My Bad," Dexter states that he has killed 67 people who "deserved to die," with Arthur Mitchell being the 67th. However, by the end of Season Four, the total known kills amounts to 93. In the Season Five Promo, "Turned Upside Down," Dexter's blood slide box has 23 slides in it when he inserts the 24th (apparently Trinity's). This implies that he did not collect blood slides from 26 of his victims at this point.
- Season Six and Seven - After killing Walter Kenney, Dexter drops his box of slides causing them to fall out of order and one to break. However, it is clear that Walter Kenney's slide is the 43rd slide of the box, suggesting that there are at least 13 unaccounted for kills between Season Five and Season Six. As of the end of Season Six, Dexter's total number of known killings is 123. By the end of Season Seven, the number is upped to 129, with six additional victims that season.
- Early Kills - It is disclosed in season eight that Juan Ryness was Dexter's fourth kill. Between Mary and Juan, Dexter killed two other people. The third person (before Juan) was the first time that Dexter brought photos of his target's victims to the site. During his next several kills, his kill ritual continued to evolve.
- Unnamed Victims - Two weeks before New Year's Eve of 2000, Dexter is seen dumping the body of an unknown man with a long beard, seemingly dressed as Santa Claus,. but it's likely that he is listed in the first box ("All in the Family - Chapter Two"). Another man had his neck sawed through with a disc power saw, possibly Peter Thornton or someone listed in the first box (Promo "Serial Killer by Night").
Early Cuts Timeline
- Gene Marshall - With the introduction of Dexter Early Cuts, some inconsistency exists in the timeline when characters were killed. The major problem is that, in Early Cuts, Alex Timmons was killed in 2003 and Gene Marshall was killed in 1993. Despite Gene Marshall being killed prior to Dexter taking blood slides, he had a blood slide in Dexter's box ("Return to Sender").
- Harry's Death - In the flashback before Dexter kills Juan Ryness, Debra is seen celebrating a birthday, wearing her glasses, while Harry is alive and well. Then, in "Early Cuts: Gene Marshall," Debra is seen on her sixteenth birthday, not wearing her glasses. In this Early Cuts' episode (which took place in 1993) Dexter mentioned that Debra was the only family he had left, so it is implied that Harry had died by that point.
- Peter Thornton - According to "Early Cuts: Dark Echo Trailer," Dexter buried his father, attended medical school, and killed Peter Thornton in 1994.
- Cindy Landon - Dexter used a chainsaw to kill her in 2004 ("Early Cuts Cindy Landon").
- Dexter's first and last (known) victims are female.
- Although not actual victims, "All in the Family" reveals that Dexter used to mutilate and dismember his sister's dolls and, at one point, is shown setting fire to a stuffed bear.
- It's Alive! is the only season premiere where Dexter did not kill anybody, although there were two attempts. Similarly, The Big One is the only season finale where Dexter kills no one.
- Dexter's first kill, Mary, was to save Harry Morgan. Ironically, Dexter's final known kill was Debra Morgan, Harry's daughter.
- Only two of Dexter's victims appeared alive in more than one season - Camilla Figg and Debra Morgan. Incidentally, both were mercy kills and both were female. Both Brian Moser and Travis Marshall appeared in seasons after their deaths, however, Brian appeared as an illusion and Travis appeared as a corpse.
- Of the eight main antagonists, only two were not killed by Dexter. Jordan Chase was stabbed in the chest by Lumen Pierce, and Isaak Sirko was shot by George Novikov. Despite this, both of them were disposed of by Dexter. Isaak Sirko was dropped into the Gulf Stream so that he could be with his lover, Viktor Baskov (who was previously killed by Dexter).
- Brian Moser didn't have a blood slide taken, and his body was left as a staged suicide. It is unknown what Dexter did with Lila West's body after he killed her, but he didn't take blood from her.
- Miguel Prado's crime scene was staged to look like he was murdered by The Skinner, so there was no blood taken.
- Dexter lost Travis Marshall's blood slide at the crime scene, which was later found - broken and partially burned - by Maria LaGuerta. Travis was the last person that Dexter took a blood slide from, as he later abandoned this practice when he killed Ray Speltzer..
