Florida killer clown cold case: Woman who murdered romantic rival in costume released from prison

Sheila Keen-Warren, 61, was released from prison just 18 months following her guilty plea to the second-degree murder of Marlene Warren while dressed as a clown delivering carnations and balloons.

"We are absolutely thrilled that Ms. Keen-Warren has been released from prison and is returning to her family," Greg Rosenfeld, Kenn-Warren's lawyer, told the Associated Press. "As we've stated from the beginning, she did not commit this crime."

The victim's son, Joseph Ahrens, and friends were home at the time of the shooting and claim a person dressed as a clown delivered the balloons and flowers before shooting Marlene in the face.

Keen-Warren went on to marry the husband of her victim, Michael Warren, whom she worked for.

Witnesses believed that the two were having an affair at the time of Marlene's murder, though they both denied it.

Michael was initially a suspect, but was never convicted.
