Unusual Suspects: Deadly Intent is an American television documentary program on Investigation Discovery. The series, which ran for one season, debuted on October 4, 2017 and ended in January 2018. It served as a sequel to Unusual Suspects. Like its predecessor, the new program also showcases the intricate investigations that led to the arrest of unusual killers – people who most of the time never even had a police record – and how those cases were complicated and challenging even for experienced people working in law enforcement.
