‘Killer Clown’ Suspect Sheila Keen-Warren Pleads Guilty to 1990 Murder of Woman

Sheila Keen-Warren pleaded guilty to being the long-sought "killer clown" who murdered a Florida mother 33 years ago. In 1990, Marlene Warren answered the door of her home to find a woman dressed as a clown delivering flowers and a balloon reading "You're the greatest." Suddenly, the clown pulled a gun and shot Marlene in the face. She later died. The case went cold until Sheila was arrested in 2017 after her hair fiber was found in the getaway car.
