Let The Devil In (2025 TV Series)

“Let the Devil In” is a four-episode true-crime documentary series premiering on August 31, 2025, on MGM+. Set in Jefferson, New Jersey, it re-examines a horrific 1988 murder-suicide case in which 14-year-old Thomas Sullivan Jr. stabbed his mother, Betty Ann, before taking his own life. Following the crime, accusations of Satanic ritual and demonic possession stirred fear during the peak of the 1980s Satanic Panic. Decades later, the series brings together witnesses, investigators, and community members as they attempt to separate fact from folklore and discover what really happened.
