After 27 years, authorities arrested Sheila Keen-Warren for the 1990 killing of Marlene Warren by an assailant disguised as a clown. Warren answered the door to someone dressed as a clown who handed her balloons and flowers, then pulled out a gun and shot her in the face. Marlene Warren died at the hospital 2 days later.
Sheila Keen became a suspect when authorities found out she was having an affair with Marlene’s husband, Michael. She eventually married him, but no arrest was made for decades.
In 2014, new DNA evidence was uncovered by modern technology that tied Sheila Keen-Warren to the crime. She was arrested in Virginia in 2017, still married to Michael Keen. The case has been pending since then, but was scheduled to go to trial in the coming weeks.
Mrs. Keen-Warren will be sentenced to 12 years in prison, with some 6 years of credit since her arrest. The charge was under the old guidelines, and before the rule that requires prisoners to serve 85% of their sentences, so she has completed a substantial portion of her sentence. She will likely be out in less than 2 years. Her attorneys insist that she still claims innocence, but accepted the deal to avoid the risk of trial. With as much credit, and imminent release, the plea agreement makes a lot of sense for her. While she may protest her innocence, she has now plead guilty and been convicted of the offense. The family finally has closure.
In 1990, Marlene Warren was celebrating her birthday when the door rang and she went to answer it. Standing outside with a person dressed in a clown suit carrying balloons and flowers; apparently in celebration of her birthday.When Marlene reached for the gift, the clown pulled out a gun and shot her. She later passed away from the injuries and detectives began an investigation. They initially looked at Marlene’s husband, as they hear there had been marital difficulties.
The investigation soon centered on Sheila Keen, whom detectives discovered was having an affair with Michael Warren, Marlene’s husband. Not only that, witnesses stated they had seen Ms. Keen buying a clown suit two days before the murder and she was also seen purchasing flowers at Publix. In spite of these connections, detectives did not feel confident that they would be able to prove their case and did not make an arrest, and the case went cold

Fast forward 24 years to 2014, and the Cold Case unit of the Palm Beach County Sheriff’s Department reopened the case to take another look. New technology allowed them to uncover DNA evidence that was able to able to affirmatively link Sheila Keen to the crime. Detectives also discovered that she had since married Michael Warren, and that the two were living together in Tennessee. Detectives arrested Sheila Keen Warren on a warrant for murder this week in Virginia. Her husband was reportedly with her, but has not been charged with anything at this time. Sheila Keen Warren is notably smiling in the mug shot when she got arrest. There is no indication if she gave a statement to law enforcement when she was picked up, but she’s probably impressed to have gotten away with it all these years.
