Signs of a Psychopath

After the shooting deaths of father, mother, and two adolescent boys in their suburban Baltimore home, investigators realize it's not a robbery gone wrong but rather the execution of a loving family, done by a callous and calculating psychopathic killer.

An early morning fire inside an apartment complex soon reveals something worse? The dead bodies of a young woman and an infant boy. Detectives find a psychopath who appears polite and gentle, then later as a pawn of imagined demons.

Police first arrest a man for discharging a firearm and soon discover dead bodies inside his apartment. Detectives try to make sense of the bloody crime scene and a psychopath willing to murder those closest to him.

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."
