Killer Instinct (2011): Two young men vanish from a New Hampshire farm. The last person to see them alive is an eccentric and beguiling local woman who was dating both men. Little do police suspect that she lured these men and possibly others to her farm, tortured them, and then killed them. When she's finally caught and the defense claims she's insane, Mark tries to prove otherwise. To him this deadly woman is something else entirely, and among the rarest types of offenders, a female serial killer.
