house, he tells them that he has a storage unit under a highway. Nathan Marten (Jason Kaufman) is a pedophile who approaches Astor while Dexter, Rita, and the kids were shopping at a grocery store. Later, while at the beach, Dexter sees Marten taking pictures of Astor. While initially hesitant to kill Marten because he does not satisfy "The Code of Harry" (he is not a killer), Dexter strangles him after it becomes apparent that Marten will eventually try to rape Astor. Possibly because he is not a murderer, Dexter does not take (or is at least not shown taking) a blood slide sample from him. Ethan Turner (Larry Sullivan) married wealthy women, killed them, and took their money and assets. Ethan has killed at least two wives. Miguel Prado tried to prosecute him, but could not, supposedly due to lack of evidence. Miguel brought his frustrations about the case to Dexter's attention, who investigated as well and decided to seek out Ethan in Bimini. Upon boarding the same cruise ship Ethan was on, he trapped Ethan in his room, killed, and dismembered him, then got off the ship.

Miguel confronted Dexter about this, and revealed he had deliberately mentioned Ethan to Dexter in the hope he would avenge Ethan's victims, who the justice system had failed. Having seized this opportunity, Miguel expressed his admiration and respect for Dexter for achieving through vigilantism what he had failed to do legally. Clemson Galt (Blake Gibbons) is a neo-Nazi who murdered his girlfriend for getting pregnant, as well as the family of an "Aryan defector". He was found not guilty of the killings after his associates frightened or killed all witnesses. However, he was found guilty for an unrelated armed robbery and was sentenced to 15 years in a maximum security prison. Dexter suggests Galt to Miguel Prado as a target, intending to scare Prado off by showing the difficulty and risk of such a project. To Dexter's surprise, Prado brings Galt to a Miami courthouse as an expert witness and releases him. Dexter, posing as a fellow neo-Nazi, picks him up only to capture him, and kill him. Dexter says that Galt had been
