Signs Of A Psychopath

A Russian immigrant's stabbing leads to his wife: beautiful, charming, and lethal; a runaway teen aids her boyfriend in slaughtering grandparents, Ws manhunts close in, both women's facades crumble, revealing the chilling minds of killers.

Experts look at a subset of psychopaths who are motivated by their heightened sexual urges and fantasies. This subset of offenders doesn't just enact physical violence but sexual violence toward their victims and is known as the "sexual psychopath."

A mother, her kids and friends vanish in a mystery.; a slaughtered couple's son disappears; in both cases, young men toy with police, twisting facts and stalling for time; as lives hang in the balance, the truth hides behind lies.

Teens plot the murders of their friends; one scheme involves a manipulative ex and a group bent on blood; the other, a calculating teen who brags on camera about a killing months in the making; both reveal the darkness of youth gone cold.
