his mother's death. Scott Smith (Jake Short) is a boy kidnapped from his babysitter at a mall by Arthur Mitchell. His father, Nick (portrayed by Roger Ranney) arranges a manhunt. He was rescued by Dexter before Arthur got to kill him. Later during Debra's interview with Scott, his experience helped the police to identify Arthur as the Trinity Killer. Stan Beaudry (Ian Patrick Williams) is a trucker who allegedly murdered a prostitute, but was never arrested due to contamination of the chain of evidence of the alleged murder weapon by the police. Dexter sets him up to be the primary suspect for the Trinity killer as Miami PD is closing in, and then kills him in his truck. This kill was done very hastily on scant evidence, lacking even the picture of Beaudry's victim, which Dexter acknowledges. Later, the police track the movements of Beaudry from city to city on his truck routes and find the Trinity Killer's post cards to his daughter, Christine. This clears Beaudry as being the Trinity Killer after finding he has rock solid alibis, including that he was hundreds of miles from the scene of some of the Trinity Killings at the time of the murders. They determined correctly that the DNA, murder weapon, and Lundy's files were planted, but attributed this to the real Trinity Killer (the evidence was actually planted by Dexter). Minor characters in season 5 Ray Walker (Adam John Harrington) is an FBI agent investigating Rita's death and its ties to the Trinity killer. Quinn asks him where the safe-house from the Mitchell family is, to ask them some questions about Kyle Butler. Rankin (Brad Carter) is Dexter's first kill following Rita's death. It was not, however, a murder by Harry's code, but rather an act of rage. Dexter, roaming the Miami outskirts, meets him at fuel dock store, and — as Rankin taunts Dexter's dead wife — Dexter responds by beating him to death. When done, thoughts of Harry appear, saying that the slaughter was the first human thing he had seen Dexter do since Rita's death. It is Dexter's third known inadvertent killing. The Barrel Girl Gang, a raping/killing circle folds out as the main target of Dexter for Season 5. The circle is responsible for kidnapping, raping and killing twelve women; Lumen was intended to be their thirteenth victim. Their victims were initially held captive in the campgrounds
