YMMV / Criminal Minds S 10 E 23 The Hunt

• Complete Monster: Alex Zorgen runs a Human Trafficking ring that has sold dozens of victims, mostly women, regardless of age, to serial killers and other criminals online, with said criminals killing them. In 1993, prior to creating this ring, he abducted a woman named Donna Mangold, repeatedly raping and torturing her for the next 22 years, with one of those rapes resulting in a son named Kyle. As the season progresses, Alex has Kyle stalk the BAU's newest member, Kate Callahan, by posing as an attractive high school senior online to gain the trust of her niece, Meg, and her friend, who are both 14 years old. He sends Kyle and Donna to kidnap the girls in the season finale "The Hunt", but Meg's friend escapes, which results in Alex killing Kyle without any remorse, before selling Meg. When the BAU later arrests him and asks him where Meg's captor is keeping her, he refuses to cooperate and just taunts Kate about the things her niece's captor is going to do to her.
