Signs of a Psychopath (2020)

S11E2 I Don't Belong Out Here

A troubled man walks into a police station and confesses to a horrifying massacre that wiped out generations of his own family. As detectives dig deeper, they uncover a chilling connection to an old, unresolved case. The confession unravels into something far more sinister—a narcissistic psychopath, driven by a twisted need for control, who is manipulating the investigation to engineer his own return to prison.
