Sheila Keen Warren, the shooter in Palm Beach County’s infamous 1990 “killer clown” case, was released from prison Saturday after spending about 17 months in prison near Tallahassee. Keen Warren, 61, pleaded guilty in April 2023 to being the person who dressed up in a head-to-toe clown costume on the morning of May 26, 1990, and shot Marlene Warren, a Wellington mother and wife, in the face.
