She was a housewife who killed her husband, Jim Watson, for infidelity.
Kaitlyn was married to Jim Watson, who was cheating on her for an unknown period of time. She eventually found out, and this led to a tragic set of circumstances where both of them ended up dead.
The police get called out to their house and find the dead couple, and they put in a call to Homicide. Detective Mike Anderson was sent to investigate the murders with assistance from Forensic Blood Spatter Analyst Dexter Morgan. After they arrived at the scene, Mike initially thought that it was a double murder but Dexter noticed the wounds on the body and found the husband's cell phone under the couch.
Dexter determined from the photo of the husband with the nude woman on the cellphone that the wife probably committed the murders. This was confirmed after Dexter lifted the wife's body and found the gun used to kill both her and her husband. After the case was solved, Lieutenant Debra Morgan moved into the house at a low price due to the recent murders.
