Chilling Three-Part Series Examines the Murder of a Florida Woman by a Person Dressed as a Clown

NEW YORK - May 8, 2025 - The shocking and eerie limited true crime docu-series, The Killer Clown: Murder on the Doorstep, is set to premiere on Thursday, June 5 at 10pm ET/PT on SundanceTV and will also be available as a full-series binge on Sundance Now and AMC+ the same day. Airing weekly on SundanceTV, the series chronicles the jaw dropping true story behind the murder of Florida resident Marlene Warren, a young wife and mother, who was brutally gunned down on her own doorstep by a person dressed as a clown.

With rumors of infidelity and an unhappy marriage, Marlene's husband Michael Warren emerges as the prime suspect, but with a solid alibi detectives can't prove his involvement, and the case goes cold. Three decades later there's a shocking twist - Michael's alleged mistress Sheila Keen is arrested for Marlene's murder accused of donning the clown disguise. In May 2023 Sheila pleaded guilty just before trial. Case closed? Or does this guilty plea raise as many questions as it answers?

The three-part series re-examines the case uncovering a complex web of love, betrayal, and deceit. Through interviews with investigators, attorneys for both the defense and prosecution, Marlene's son Joe and others close to Michael and Marlene, the series unravels the chilling motives behind the murder and the quest for justice that spanned nearly 30 years.

The Killer Clown: Murder on the Doorstep is directed and produced by Ellie Merz (Untold). A Sundance Now Original, the true crime docu-series is produced by Flicker Productions and distributed by BossaNova Media. It is executive produced by BossaNova Media's Paul Heaney, Sky's Emily-Jayne Wilde and Jack Oliver, as well as Colleen Flynn.
