Plot Synopsis

CITIZEN P.I. is an investigative series that examines the phenomenon of amateur sleuths who have played major roles in cracking real unsolved cases. This six-episode series showcases the colorful personalities of people who dive headfirst into the rabbit hole to solve violent crimes. While some people may view this simply as a hobby, these digital detectives can play a significant role in the apprehension of real criminals. Each 40-minute installment follows one or more amateur sleuths as they investigate a case that poses a significant interest to them: a series of dead ends leaves a killer on the loose in the hills of Malibu, California; a victim is found buried deep in the woods of East Texas; and a woman's controversial death is ruled a suicide, leaving a Florida community divided for more than a decade. When a case goes cold, justice might seem like it's out of reach. But sometimes, one brave Citizen P.I. can make a difference. The first three episodes dropped on Tuesday, July 27, 2021 on discovery+, with a new episode debuting each Tuesday through August 17:
