Clown Killer Pleads Guilty to 30-Year-Old Murder

Sheila Keen-Warren admitted in court to killing Marlene Warren in 1990 while posing as a clown in Florida.
Keen-Warren was sentenced to 12 years in prison for second-degree murder but has already served six years and will likely be released in two years.
Marlene Warren's son said he saw no remorse from Keen-Warren at her sentencing.
Marlene Warren was shot in front of her son by a clown holding balloons and flowers who came to her door.
The murder went unsolved for 24 years until investigators learned Keen-Warren had married Marlene's widower and worked for him when Marlene was killed.
