You know, when we started this whole thing, I wasn't sure, I just, you know, I didn't know if you had it in you. ...Last couple nights, I mean, you've come a long way. I'm proud of you, Toby. I really am.

David Roy Turner was a serial killer and copycat who was the dominant partner of a two-person killing team. He appeared in Season Eight of Criminal Minds.


David's father Nate was a boat mechanic in Miami and died twelve years prior to "The Apprenticeship". At some point, he developed a sexual preference for teenage boys. In 2002, David was arrested for raping an underage male prostitute and was put on a work detail with another inmate named Rudy Stein, who had killed a number of prostitutes in New York and tutored him on how to kill without getting caught. They maintained close contact after David was released in 2006. When Rudy died of a massive stroke in prison on July 2011, David snapped and decided to tutor a young killer just as Rudy had taught him. Sometime on or prior to October 2012, he came across the budding psychopath Toby Whitewood, who had been murdering dogs in the neighborhood and whom David somehow identified as the killer. He gained Toby's trust by rescuing him from a teenage boy named José Aguilar, who was attacking him while saving a dog. Afterwards, David started teaching Toby how to be a killer. All the while, he began developing secretive feelings for Toby.

Modus Operandi

David mimicked Rudy Stein's method of killing, which involved snatching prostitutes in their early twenties off the street, intimidating them into compliance. He would then kill them with a blow to the head with a hammer, although he tortured his second victim, Shawna Radford, by wrapping a plastic bag over her head beforehand, something incorporated by Toby. In the case of his first fatal victim, Vicky Thomas, he repeatedly bit her before killing her, dumped her body in a dumpster, placed a plastic bag over her head post-mortem, and rolled the body around in garbage as a forensic countermeasure. After killing his first two victims, he dumped their bodies in areas they did not operate in. When he killed Toby, he strangled him with his bare hands in a blind fit of rage. When he attempted to kill José Aguilar, he clubbed him over the head with a hammer, and he tried to do the same with Hollie Riggio but was stopped by the BAU before he could. In the case of his first victim, the male prostitute, he raped, bit, punched, and kicked him during and after the rape.

Real-Life Comparison

David's second murder seems to have been based on the M.O. of Lonnie David Franklin, a.k.a. "The Grim Sleeper". Just like David's murder, Franklin targeted prostitutes, solicited them as a ruse, dumped their bodies in dumpsters, and covered them in trash.
