David Roy Turner

"When we started this thing, I didn't know if you had it in you. But the last couple nights, you've come a long way. I'm proud of you, Toby. I really am."

David Roy Turner was a budding serial killer who appeared in Season Eight of Criminal Minds.

Background
David's father was a boat mechanic, who died twelve years prior to "The Apprenticeship". David was arrested for assaulting an underage male prostitute and was put on a work detail with another inmate named Rudy Stein, who tutored him on how to kill without getting caught. They maintained close contact after David was released. When Rudy died of a massive stroke in prison, David snapped and decided to tutor a young killer just as Rudy had taught him. He eventually came across the budding psychopath Toby Whitewood, who had been murdering dogs in the neighborhood. Gaining Toby's trust by rescuing him from a teenage boy named Jose Aguilar when he attacked him while saving a dog, 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, snatching a prostitute off the street, intimidating her into compliance, and then sexually assaulting her, often biting her. He would then kill the victim with a blow to the head by a hammer, before dumping the body. This M.O. would later get mixed with Toby's suffocation technique while they were together.
