Despite her release, Aronberg emphasized that Keen-Warren will always be considered a convicted murderer.

Sheila Keen-Warren, 61, was released from prison on November 2, 2024, after serving approximately seven years for the second-degree murder of Marlene Warren, a case that has drawn significant attention due to its unusual circumstances.

Marlene Warren was shot in the face on May 26, 1990, by a clown delivering balloons to her home, an event witnessed by her son, Joseph Ahrens.

Prior to her death, Marlene had expressed fears about her safety, telling her mother, 'If anything happens to me, Mike done it,' suggesting her husband Michael's potential involvement.

At the time of the murder, Keen-Warren was employed by Michael Warren, Marlene's husband, and they later married in 2002, complicating the investigation.

Witnesses indicated that Keen-Warren and Michael were having an affair at the time of Marlene's death, a claim both have denied.

Investigators had long suspected Keen-Warren but only arrested her in 2017 after improved DNA testing linked her to the getaway car used in the murder.

The getaway car, linked to Michael Warren's car lot, was found abandoned with hair-like fibers, although the reliability of this evidence was contested by Keen-Warren's defense.

Palm Beach County State Attorney Dave Aronberg acknowledged weaknesses in the case, citing the lengthy delay before trial and the loss of key witnesses over the decades.

Evidence against Keen-Warren included a clown suit purchased shortly before the murder and balloons bought from a store near her home, further suggesting her involvement.

Keen-Warren accepted a plea deal to avoid a potential life sentence at trial, maintaining her innocence throughout the case.

The bizarre circumstances of the murder will be featured in an upcoming episode of People Magazine Investigates titled 'Sex. Clowns. Murder,' airing on November 4, 2024.
