Bay Harbor Butcher 18
The Bay Harbor Butcher 18 was the name given to the eighteen dismembered bodies that were found by scuba divers off the coast of Miami. After recovery, they were laid out in a field morgue to examine and identify. Investigators never discovered 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")
- 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 unloaded. ("Nebraska")
- Alberto - When Alberto pulled a gun and began to threaten and rob Cuban migrants, 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")
- Andrew Briggs - Dexter stabbed Briggs during a struggle in a motel room. ("A Beautiful Day")
- 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")
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. However, the FBI confirmed that Dexter was not responsible ("Hello Bandit").
- Dexter Morgan - In the series finale, Dexter was believed to have committed suicide by sending his boat into Hurricane Laura. In fact, he only faked his death.
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")
- Jerry Rames (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). However, she likely would've killed her husband, even if she hadn't been interested in Dexter. ("Dexter Early Cuts: Cindy Landon")
- Jason Riech (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 his victim 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 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 - Killed on the orders of Little Chino. This murder could have prevented if Dexter had killed Chino earlier, which he failed to do as Chino escaped from him. ("Waiting to Exhale")
- Unidentified man - Shot by his elderly father who panicked because of The Bay Harbor Butcher news and mistook his son when he came home from the night shift late. Note: This incident was mentioned by Deputy Chief Matthews, but he did not say whether the man 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. ("Dex, Lies, and Videotape")
- James Doakes - Killed in an explosion by Lila West 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, whom 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 coerced 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 hospital. 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 - After Maria discovered that Dexter was The Bay Harbor Butcher, she ordered Debra to shoot him. However, a very emotional Debra killed Maria instead. ("Surprise, Motherfucker!")
- Shawn Decker - A murderer who was beaten to death by Zach Hamilton, after Dexter taught him the code. ("Are We There Yet?")
- Max Clayton - Instead of killing Oliver Saxon after kidnapping him, he left him alive to be arrested. When Max found Saxon tied up, Saxon pretended to be a helpless victim and tricked Max into releasing him. Saxon then stabbed Max in the heart. Jacob Elway even points out that Dexter is partly responsible for his death. ("Monkey in a Box")
- Debra Morgan - Shot by Oliver Saxon moments after Max Clayton's death. She was admitted to the hospital and, although in good condition at first, a blood clot deprived her brain of oxygen. 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 returned and shut off Debra's life support. Despite the fact that she is a direct kill, she is also considered an indirect, for if Dexter had killed Saxon earlier, Debra would not have been shot. ("Remember the Monsters?")
- Possible Hurricane Laura Casualties - In the series finale, Dexter caused a flight to be delayed while trying to get Jacob Elway off Hannah's trail. The flight was further delayed because a hurricane was too close for the plane to take off. Although no casualties of the hurricane are mentioned, there is a chance some people died who were supposed to be on the flight out of Miami.
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 - Brian tracked Dexter for several years, aware that he was a serial killer. Over this time, he learned of Dexter's methods and replicated his kill room when he captured Debra Morgan.
- James Doakes - He knew that Dexter killed Esteban and Teo Famosa. He saw Dexter enter the cabin where he snapped Esteban's neck, and then emerge to shoot and kill Teo. Prior to that, Dexter killed Jose Garza with Doakes only a few feet away. A plastic sheet was up to block Doakes' view 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 Cuban Migrants - They witnessed Dexter kill Alberto. None of them could speak English well, but they were unlikely to turn Dexter in, not only because Alberto had threatened them, but because they might be deported by authorities.
- Several Shooters - Witnesses of a crime, but not of Dexter's involvement. They were present at the shooting range when Dexter killed Oleg Mickic, but none of them observed Oleg being stabbed by Dexter.
- Evelyn Vogel and Debra Morgan - They watched Dexter stab A.J. Yates through a mattress with a curtain rod.
- Joey Quinn and Angel Batista - They watched video footage of Dexter kill Oliver Saxon with a pen.
- 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 - Harry unexpectedly walked into his garage as Dexter dismembered Juan Ryness, and Debra walked into a church as he stabbed Travis Marshall. (Maria LaGuerta also found a kill room in a shipping container but it was deserted. When she returned to it later, she was killed by Debra.)

- Tony Rodriguez - (Early Cuts) Dexter arrived at his house, only to find a new resident - 'Julian Belows.' Dexter then stated, "His kind rarely leaves forwarding addresses." (Dexter Early Cuts)
- Sam Duke - (Early Cuts) Shortly after picking him to be his next target, Doakes walked into the station with him, having arrested him. (Dexter Early Cuts)
- Jeremy Downs - Dexter attempted to kill him, but decided not to after Jeremy said he 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 killed himself in a fashion similar to how he killed his victims. ("Circle of Friends")
- Jimmy Sensio - Dexter suffered from performance anxiety and let him go, giving the excuse that he was blind. Jimmy then fled town. Dexter had taken a blood slide but he cleaned it since he didn't complete the kill. (It's Alive!)
- Robert Brunner - Dexter almost killed him, but he discovered Brunner was wearing an ankle bracelet, and therefore not one of the men responsible for abusing Lumen. ("First Blood")
- Joey Quinn - Dexter intended to kill him because he believed he was surveilling him. However, when he was about to abduct Quinn, Dexter was instead captured by Stan Liddy, who was actually the one watching him all along. ("Hop a Freighter")
- Brother Sam - Dexter stalked him to a house, where Sam apparently shoots and kills Nick. Dexter then followed Sam to his auto shop, intending to subdue him with M99. However, Sam is alerted of Dexter's presence by his guard dog, Eli. When Dexter followed Sam into the garage, Nick was there, still 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, Jonah revealed that Rebecca Mitchell killed herself because of their mother's abuse, and he had killed his mother because of this. Dexter decided to spare him, despite Jonah begging to be killed. ("Nebraska")
- Louis Greene - After Dexter injected him, he started seeing black and met with Deb to talk about his feelings. Unknown to her, Louis was passed out in the trunk. After Deb left, Dexter left Louis on a bench. ("Sunshine and Frosty Swirl")
- Hannah McKay - Dexter had her tied down on the kill table, but when she told him to do what he had to do, he cut her free. They ended up having sex on the very table where he almost killed her. ("Do the Wrong Thing")
- Isaak Sirko - Dexter went to Viktor's apartment where Isaak was staying to kill him, but instead found an Unnamed Hitman, whom he killed. ("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. Later, Isaak killed Caffrey himself, after Dexter led him into a trap.
- Joe Jensen - Dexter attempted to kill him but didn't, partly 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 tried to convince her to shoot Dexter. Dexter even told Debra, "You're a good person...Do what you gotta do." Impulsively, 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. There, he found several tools, seemingly proving Sussman's guilt. Immediately after finding the tools, Dexter heard a creak in the back of the building. He went to investigate and found Sussman hanging from a hook. He later discovered that Sussman had been coerced to murder Leonard Welks by The Brain Surgeon, and was killed afterwards.
- Miles Castner - Hannah asked Dexter to kill Miles, but then changed her mind. However, when Dexter learned that Miles was abusing Hannah, he boarded his yacht, armed with a knife. However, Hannah had just killed Miles herself.
- Zach Hamilton - Dexter initially planned to kill Zach because he had killed Norma Rivera and attempted to kill his father. At the last moment, Dexter realized how similar he and Zach were, so he cut him loose and decided to train him.
It took more than one attempt for Dexter to kill these targets.
- Little Chino - (3 attempts) Dexter accidentally woke him up while cutting his cheek, and Chino escaped. Dexter tried to kill him again with a tranquilizer gun, but Chino knew he was coming for him and Dexter was chased by his gang members. Soon after, Dexter managed to capture and kill him.
- Santos Jimenez - (2 attempts) Dexter brutally beat him in The Swamp (tavern) and almost killed him with a knife until Lila phoned him and talked him out of it (however, she thought he was going to use heroin). Later, when Dexter was walking out of Starlight Lanes, Jimenez attempted to kill him, but ran away when Lila yelled for help. Dexter then followed Jimenez to the Cabin in the Everglades, and dismembered him with a chainsaw.
- Fred Bowman - (2 attempts) Dexter went to his house to kill him, but found him fighting with Oscar Prado. Dexter's appearance surprised both men and Freebo was able to break free and escape. Prado turned his attention to Dexter who killed Prado in self-defense. Dexter tracked Freebo to Teegan Campbell's home, choked him until he passed out, and dragged him into the garage. He wrapped him in plastic and set him upright on a picnic table. Dexter stabbed him in the neck with the same bayonet that Oscar Prado had attacked Freebo with the day before.
- Benito Gomez - (2 attempts) Dexter was ready to ambush him near the bar which Benny frequented but, being sleep-deprived, he fell asleep. Dexter later succeed in injecting Benny with M99 in the trailer park where Benny lived.
- Jonathan Farrow - (2 attempts) Dexter was ready for the kill but as he was trying to get Farrow out of the club, he noticed that Joey Quinn was also there and preferred not to risk it. Instead, he killed Farrow the next night.
- Arthur Mitchell - (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 - (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 - (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 James 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 - (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 - (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 - (3 attempts) After discovering his "lair," Dexter later returned with the intention of killing Yates. However, he had already left, but Dexter found and saved one of his victims, Janet Thorton. 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 - (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, often with a method that deviated from his normal modus operandi.
- Brian Moser was his brother, whom he killed by slashing his throat and hanging him upside down, causing Moser to die from exsanguination. This was the method that Moser used to kill his prostitute victims. ("Born Free")
- Lila West was his ex-lover whom he killed by administering a spinal epidural (to ensure a painless death), and stabbing her in the chest. ("The British Invasion")
- Miguel Prado was briefly his 'best' friend with whom he bonded with over killing. After Miguel turned on him, Dexter killed him by strangulation with a wire to emulate the modus operandi of The Skinner.("I Had a Dream")
- Arthur Mitchell was a fellow serial killer whom Dexter initially admired. After Arthur murdered Dexter’s wife, Dexter killed him with a hammer while playing his favorite song. On a side note, the hammer was part of Mitchell’s sequenced killings.("The Getaway")
- Jordan Chase was the founder of the Barrel Girl Gang (men who raped and tortured Lumen Pierce, among others), He was killed by Lumen with Dexter’s assistance, using his modus operandi. However, the killing deviates slightly from Dexter’s method, as Chase is completely clothed, and belted to the table. ("The Big One")
- Travis Marshall was a fellow serial killer who was helping Dexter find Professor Gellar. Unknown to Dexter, Travis had actually stabbed Gellar to death three years prior. ("This is the Way the World Ends")
- Maria LaGuerta was about to be killed by gunshot in order to frame her in a cross-killing with Hector Estrada. However, Dexter was interrupted by Debra, who shot Maria herself. ("Surprise, Motherfucker!")
- Oliver Saxon was the son of Evelyn Vogel. Dexter killed him in full view of a camera with a pen to the carotid artery. Dexter managed to make it look like self defense and avoided incarceration. On a side note, this is the only kill to be witnessed by Angel Batista and Joey Quinn. ("Remember the Monsters?")
- Phil Bosso - Initially, Dexter believed him to be the Phantom Arsonist, so he stalked him to find evidence. Instead, he found proof that Bosso couldn't be responsible for the killings because he had an alibi. ("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 turned 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 interrupted before the sedating act by Debra's phone call. She invited him to celebrate her transfer to Homicide. In the restaurant, Dexter noticed Guerrero and followed him into the bathroom. Dexter considered whether it was necessary and safe to use his kill room to kill Guerrero, and then kill Chambers at a later time. He decided against it, concluding that Guerrero himself chose "to live in a 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 briefly thought that he could easily "help" Rita with the neighbor's noisy dog. It's possible that he was not thinking of killing the dog exclusively. ("Popping Cherry")
- Lucas - Despite stalking Downs in his attempt to kill Lucas, Dexter had no plan to rescue him which left Lucas in great danger. Dexter, though, was far more benevolent than usual and saved him. ("Popping Cherry")
- Suspects - Jose Molina, Pedro Famosa, Manuel Valdes, and Ramon Fernandez were suspects in the human smuggler case until Dexter picked up Jorge Castillo ("Love American Style")
- Neil Perry - Dexter planned to kill The Ice Truck Killer so when Perry falsely confessed to being ITK, he put himself in danger. However, there wasn't much of a window between when the department found Perry's planted evidence and his arrest, so it's unlikely Dexter would've had the chance to kill him. ("Circle of Friends")
- Allison Sera - Her life was dependent on whether Dexter killed Roger Hicks. Considering his problems with the Bay Harbor Butcher Case, Sera was lucky that Dexter did kill Hicks. ("An Inconvenient Lie")
- John Henry - He was an attempted victim by Ken Olson, who was inspired by Dexter's deeds. ("Dex, Lies and Videotape")
- James Doakes - Dexter remarked to him that he could "unleash the beast at any time." 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 of Lila West, she kidnapped them to lure Dexter to her loft where she could burn him and the children alive. ("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 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." Miguel then 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 more properties, the two briefly fought after he threatened to kill him. During the ensuing struggle, Dexter's threats became more serious and 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 to his son (mostly a bluff). ("Blinded by the Light")
- Kyle Butler - Because his name was the same as Dexter's alias, he was in danger of being killed by Trinity, but Dexter indirectly prevented it. ("Hello, Dexter Morgan")
- Elliot Larson - While Dexter was packing his things to move into Debra's apartment after the death of Rita, Elliot stopped by and asked whether his help was needed. Dexter dropped the kitchen knives and, annoyed, paused with his hand holding a knife a few inches from unsuspecting Elliot. He was clearly thinking how much he hated Elliot, while trying to suppress the urge for murder. ("Hello Bandit")
- Barry Kurt - Dexter, believing that Astor and her friend Olivia had been kidnapped, pulled Barry out a patrol car and demanded to know where they were, threatening to kill him. Later, Dexter learned that Barry was abusing Olivia so Dexter beat him up and ordered him to leave her mother. He told a terrified Barry, "If you ever come back, believe me, I wont go easy on you next time," implying that he would kill him. ("Teenage Wasteland")
- Suspect - While Dexter tried to get a DNA swab from an uncooperative suspect, Dexter grabbed him by the neck. Although it is doubtful he was going to kill the man, the gesture was very hostile, especially considering that Dexter had already imagined killing someone two times that very day. ("Buck the System")
- Truck Driver - While driving away from a grocery store where he had talked to his sister for the first time in months, Dexter was cut off by in traffic. Dexter proceeded to get in front of the man and both of them pulled over. He then went to the man and angrily put his hands around his neck, slamming him into his seat. However, when he saw a young boy in the backseat, Dexter went back to his car and drove off, still furious. ("A Beautiful Day")
- Evelyn Vogel - Dexter threatened to kill her, but was likely bluffing, as pointed out by Vogel herself. ("A Beautiful Day")
Below are characters killed by Dexter in his illusions, imagination, and dreams.
- Lipsey - Beaten to death in a dream ("The Dark Defender").
- Welsh - Beaten to death in a dream ("The Dark Defender").
- Santos Jimenez - 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 is the only one of Laura Moser's Killers to be killed after Dexter dreamed of it.
- Juan Ryness- 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 a representation of his darkness ("Nebraska"), but he had already been killed him ("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 - 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").
Suggested to Him
- 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 refused 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 while 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 but Dexter refused, believing that Jonah had a conscience. ("Nebraska")
- Hannah McKay - Debra asked Dexter to kill her ("Chemistry"), but he refused (because he was dating her).
- Ramon Prado - Suggested by Dark Passenger as Harry Morgan. ("Do You Take Dexter Morgan?")
- Lumen Pierce - Suggested by Dark Passenger as Harry Morgan. ("Practically Perfect")
- Laci - Suggested by Dark Passenger as Brian Moser .("Nebraska")
- 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's unknown if Buddy was the same dog that chased Dexter, causing him to fall on spikes and badly injure himself. ("Father Knows Best")
- Unknown Animals - While confronting young Dexter about Buddy, Harry mentioned that a lot of other bones were buried in Buddy's grave. ("Dexter") During his teenage years, Dexter secretly killed animals. 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 to 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 deer after Harry handed 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 frequently hunted in his teenage years as Harry chose it as a way to channel Dexter's urge to kill. Dexter likely killed dozens of various animals legally as a hunter. (Boar hunting was once mentioned.) 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's implied that Dexter ate at least one, but only Rita was viewed smashing a crab claw with a mallet. The seller had fresh cooked the crabs. ("Dexter"). (In Dexter: The Game, he smashed dozens.)
- Mosquito - One is shown in every opening since "Crocodile." It's crushed by Dexter, leaving a drop of blood.
- Raccoon - Dexter killed and set up a raccoon on the road in order to lure Boyd Fowler to him. Boyd immediately ascertained that the animal was killed elsewhere and was not road kill. ("Hello Bandit")
- 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 near Bay Harbor. ("Return to Sender").
- Rats - They lived in the vacant Angel of Mercy Hospital where Dexter found Tony Tucci. ("Let's Give the Boy a Hand")
- 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, or Dexter's personal choice.
- Mary - Mary was an Angel of Death who killed by overdosing sick or elderly patients with morphine, under the excuse that she was helping them. Harry pointed her out to Dexter who took action, wrapping a room in her house in plastic, readying her for a kill. This one was a bit messy but certainly the most meaningful as it was his first human kill. Dexter stabs her multiple times until she was dead. ("Popping Cherry")
- Juan Ryness - Juan was a pimp who beat one of his prostitutes to death. Being one of Harry Morgan's sought after targets, Dexter thought the best way to make his father happy would be to kill Juan. So he tracked him down and Harry caught him in the act of dismembering his body, which sickened him. Shortly thereafter, Harry committed suicide as he couldn't live with himself after seeing what Dexter was capable of doing to another human being, and realizing he had a part in it.
- Alex Timmons- Alex was a former sniper for the Marines who was discharged and then killed four random, innocent people by sniping them. He may have been arrested on suspicion of doing so and then released, which would explain how he came into Dexter's sight. Dexter killed him with a single stab to the chest with an USMC combat knife, a reference to Alex's being in the marines and collected his very first blood slide. In the Dexter Early Cuts series, Alex had murdered three children, though this was not canon in the Showtime's 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 serial killer. To get his brother's attention, he murdered prostitutes 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, when he was released and took on the alias Rudy Cooper from a man he had killed. Brian desired to reunit with his brother after finding out that the two of them were both killers. 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 unconscious, so that he wouldn't know what 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 was 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. Dexter eventually found Santos working in a bar in Naples. When the two finally meet, Dexter played into finding out more about Santos until viciously attacking him and nearly killing him, but decided not to at the last moment. This created a problem, as Santos later tried to kill him at Starlight Lanes. This failed and only prompted Dexter to follow him to an abandoned cabin, where he sawed Santos into pieces like he had done to Dexter's mother long ago. Dexter collected a blood slide from Santos, but his blood slide was "lost."
- Lila West - Lila was a fiery extrovert who introduced herself to Dexter at a NA meeting that he attended after pretending to be heroin addict to Rita (to divert suspicion when he framed Paul Bennett). An outgoing woman with a British accent, it's later revealed that Lila was an arsonist. She caused a breakup between Rita and Dexter which led to her being in a relationship with Dexter. He listened to Lila's advice and tried to control his urges (although she thought his urge was to shoot heroin). Before long, she became obsessed with Dexter and ended up using Batista when he didn't want to see her anymore. Dexter chose to kill Lila due to his failed attempts to get her to back off, her murder of James Doakes, and her threats to the lives of Cody and Astor. Dexter tracked Lila to Paris, stabbed her in the heart, and zipped up her body in a plastic garment bag. He first insured that she didn't feel any pain with a spinal epidural, and didn'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 Miguel killed Ellen Wolf for threatening his career and then targeted Maria LaGuerta because she discovered he killed Ellen. Dexter killed Miguel with a metal wire, wrapped around his neck. Dexter didn't take a blood slide from him. He does, however, remove several patches of skin off Miguel's shoulder to frame George King for his murder.
- George King - Dexter was forced to kill him when King held him captive. Of note, King was the only Dexter victim to have Dexter tied him down, on the verge of killing him. However, Dexter escaped, breaking his hand in the process. After a struggle, Dexter killed King by breaking his neck and throwing his body onto an incoming police cruiser, staging it as a suicide. Dexter did not take a blood slide because he did not have enough time to do so.
- Arthur Mitchell - Arthur Mitchell was a successful serial killer who was active for thirty years, as well as a "family man." With a known kill count of 279 people, he was one of the most prolific serial killers that Dexter killed. Dexter took a blood slide from him, making him the 24th 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 - First member of the Barrel Girl Gang to be killed by Dexter.
- Dan Mendell - Shot by Lumen, neck then snapped by Dexter
- Cole Harmon - Boyd, Dan, and Cole were members of the Barrel Girl Gang. Dexter took a blood slide from Boyd, but not Dan. He did take a blood slide from Cole, but gave it to Lumen. The other two members, Alex Tilden and Jordan Chase, were killed by Lumen.
- Travis Marshall - Travis was a serial killer who had hallucinations of Professor James Gellar. Although it was initially believed that Professor Gellar was behind the killings, it's revealed that Gellar was killed by Travis before the events of the season. Travis then accused Dexter of killing Gellar, and believed him to be "The False Prophet." Travis tried to kill Dexter in "The Lake of Fire" tableau, but failed. Then he tried to sacrifice Dexter's son, Harrison Morgan, as The Lamb. However, Dexter stopped him, and took him to the very church Travis used as a hideout. Just as Dexter stabbed Travis, Debra Morgan entered, causing Dexter to utter, "Oh God". Dexter lied about what happened and convinced her to not call the police. Debra retrieved gasoline from a gas station, and they burned Travis's body. Dexter did take a blood slide from Travis, but he lost at the scene, where Maria LaGuerta discovered it.
- Viktor Baskov - Viktor was a prominent member of the Koshka Brotherhood and a 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, Viktor was sent to Maimi in order to hold off the Colombians because his subordinate, George Novikov, failed in doing so. During his time in Miami, Viktor murdered a stripper named Kaja Soroka. While fixing a flat tire, 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 then chase them, until catching them and beating them to death. At his last victim's maze, he attempted to kill Debra Morgan. Dexter then made an attempt on Ray's life, but he was knocked out and taken to a different maze. 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 handle 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 handle. 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, and the crime lord who ordered the death of Laura Moser. For the majority of the series, Hector was in prison, until he was released by the adocacy of Maria LaGuerta, who used him as bait to catch Dexter Morgan, who she believed was the Bay Harbor Butcher. Once Hector was free, Dexter brought him to a shipping container like the one in which Hector and his subordinates killed Laura Moser. 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 shipping container. He persuaded Estrada to call LaGuerta (who believed he was dead) and summon her to the shipyard, where Dexter planned to kill them both and make it look like they killed each other. However, Debra unexpectedly appeared on scene and ended up shooting LaGuerta.
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 the Underwater Graveyard. Scuba divers later found the remains of eighteen victims. ("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 the Underwater Graveyard 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 - Cole Harmon's dismembered body was disposed of by Dexter and Lumen from his boat, while Stan Liddy took photos of them (however, he didn't have proof of what was in the bags). 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 Stream. With no ocean nearby, Dexter disposes of Norm's (The motel manager/pot farmer) body in a nearby grain silo. 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.

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 Case 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.
- Kills 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 victims appear in Dexter's box. Between the end of Season Two and the start of Season Three, the second box gained 4 slides, which implies a four-month period. Between Season Three and Season Four, 12 new slides appear, implying a twelve-month period. Between Season Five and Season Six, 13 new slides appear, implying 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 kills (including one shown at start) 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 Dexter was stalking prior to spotting Alex. This leaves at least 18 unaccounted for victims, thus possibly bringing the total of his kills to 153.
- Novel vs TV - 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 amount 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 (Mary and Debra).
- 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 Dexter's darkness 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..
- Stan Liddy was about to expose Dexter and the first rule of The Code is to not to get caught. Killing him was justified by the code. ("Hop a Freighter")
