Florida police say they have solved a 1990 cold case involving a killer clown who murdered 40-year-old Marlene Warren while holding balloons and a bouquet, while in full costume, including a red ball nose and floppy shoes. Two decades later, police say the suspect in the Palm Beach County clown murder was the current wife of Marlene’s widower: Sheila Keen Warren. She is now in custody in Virginia, awaiting extradition proceedings. Police say new DNA evidence proves that Sheila Warren allegedly shot Marlene Warren at least once in the face and then walked away. “I didn’t think that it would ever happen; there’s always hope, but I’d prefer to have her instead,” Marlene Warren’s mother, Shirley Twing, told The Sun Sentinel on Tuesday night.
