A 27-year-old cold case that haunted the quiet equestrian community of Wellington, Florida, has finally reached its conclusion, as Sheila Keen-Warren, the woman who donned a clown costume to murder a mother in cold blood, pleaded guilty to first-degree murder on April 25, 2023, bringing a dramatic end to one of the most bizarre and chilling homicides in modern American crime history. The case, which involved a killer clown, a love triangle, and a decades-long quest for justice, captivated the nation and left investigators baffled until the very end.
On May 26, 1990, 40-year-old Marlene Warren was at home with her 21-year-old son Joey, enjoying a quiet Memorial Day weekend in their cozy Wellington home. The sound of the doorbell interrupted their morning. Marlene, who had a lifelong love for clowns, opened the door to find a figure in a full clown costume, complete with an afro wig, a sponge nose, and colorful makeup, holding a bouquet of flowers and a cluster of mylar balloons.
She was overwhelmed with happiness, believing someone had sent her a thoughtful gift. But behind the cheerful disguise, the clown pulled out a gun and shot her directly in the face, leaving her dying on the doorstep as the killer fled in a white Chrysler LeBaron.
Joey Warren heard the gunshot and rushed to the door, catching only a glimpse of the clown driving away. He described the suspect as having broad shoulders and large hands, but the only concrete detail he could provide was the car. Marlene was rushed to the hospital, where she clung to life for two days before succumbing to her injuries on May 28, 1990.
The community was shattered. Wellington, known for its low crime rates and family-friendly atmosphere, was now the scene of a murder that seemed ripped from a horror film.
The investigation immediately focused on Marlene’s husband, Michael Warren. The couple’s marriage had been strained for years. Michael, a used car dealer with a criminal record for odometer tampering, was known to have a volatile temper.
Employees at his car lot, Bargain Motors, told police that Michael had openly offered $10,000 to anyone who would 𝓀𝒾𝓁𝓁 his wife, saying he would make someone rich if they got rid of her. But Michael had an alibi: he was at the racetrack on the morning of the murder. Investigators quickly turned their attention to his girlfriend, Sheila Keen.
Sheila Keen was married to Richard “Spud” Keen, a former Ku Klux Klan member who had served time for 𝒹𝓇𝓊𝑔 trafficking. She was described as headstrong, wild, and very attractive, with long brown hair that witnesses would later identify. The 𝒶𝒻𝒻𝒶𝒾𝓇 between Michael and Sheila was an open secret among their coworkers, who saw them go out for long lunches and be overly affectionate.
Michael’s own mother recalled asking Sheila if she loved her son, to which Sheila replied yes, while Michael said he loved himself. The relationship was toxic, and Marlene had told friends she feared for her life, wanting a divorce but terrified of what Michael might do.
The evidence against Sheila began to pile up. A white Chrysler LeBaron, identical to the one Joey saw, was found abandoned in a Winn-Dixie parking lot five miles from the crime scene. Inside, investigators found hairs from an acrylic wig with orange and yellow fibers, but DNA technology in 1990 was too primitive to identify the source.
Two women from a costume shop, Spotlight Capazio, told police that a woman matching Sheila’s description came in days before the murder, insisting on buying a Ruby’s clown costume, an afro wig, and clown makeup, even though the store was about to close. They identified Sheila from a photo lineup. An employee at a nearby Publix supermarket also identified Sheila as the woman who bought the specific mylar balloons just an hour and a half before the shooting.
But the most damning piece of evidence came from a lawyer named Christopher DeSantos. In 1987, Michael Warren had hired DeSantos to represent Joey on an attempted murder charge. After a successful hearing, DeSantos and Michael were walking out of the courthouse when Michael casually asked whether someone who hired a hitman to 𝓀𝒾𝓁𝓁 their wife could still inherit their estate.
DeSantos, taken aback, answered that the law prohibits a murderer from inheriting, except in cases of manslaughter or if the murderer was someone else. Then, DeSantos made a fateful comment: he said that if someone wore a clown suit, their identity would be hidden, making it difficult to get a conviction. He later regretted the statement, but investigators believed Michael took it as a blueprint for murder.
Despite the mounting evidence, prosecutors felt they lacked enough to make an arrest. Michael and Sheila continued their lives, even taking a vacation to the Bahamas together a year after Marlene’s death. In 1991, Michael went on a radio show with Joey, denying any involvement and defending Sheila.
But the investigation stalled. In 1997, a new lead emerged: a man claimed his dying father had confessed that the answers to the case could be found by pulling up a submerged vehicle. Divers searched the location but found nothing of significance.
The case went cold again.
In 2002, Michael and Sheila got married in Las Vegas, and they eventually moved to Abingdon, Virginia, where they reinvented themselves. Sheila changed her name to Debbie, and they opened a popular fast food restaurant called The Purple Cow in Tennessee. Neighbors described them as friendly and in love, seemingly having moved on from their past.
But the past was not done with them. In 2013, the Palm Beach County Sheriff’s Office received a grant to investigate cold cases, and a task force was formed with the state attorney’s office and the FBI. They submitted new evidence for DNA analysis, including samples from the clown wig and hair strands found in the Chrysler LeBaron.
The breakthrough came in 2017. A witness came forward, claiming that at a party, a drunken Sheila had bragged about getting away with murder in Florida. On December 26, 2017, Michael and Sheila were pulled over while driving back to Abingdon from Vermont.
Sheila was arrested without protest, asking only if her husband was also being taken. She was indicted for first-degree murder with a firearm, the same crime that had remained unsolved for 27 years. Her mug shot showed her smiling, a chilling echo of her teenage mug shot for a shoplifting charge.
Sheila’s trial was set for 2023, but on April 25, 2023, she pleaded guilty to the murder. Her lawyer maintained her innocence, arguing that the plea was a strategic move to avoid a potential life sentence. Under the plea deal, Sheila received a reduced sentence of 12 years, with credit for time served since her arrest in 2017.
Remarkably, her lawyer suggested she could be released as early as 2024 due to good behavior. The victim’s family was left to grapple with the outcome. Marlene’s son Joey, who had defended Sheila in the early years of the investigation, was devastated by the confession.
The case of the killer clown has been the subject of numerous documentaries, books, and podcasts, including the popular series “Mysterious Hook,” which detailed the bizarre twists and turns of the investigation. The murder weapon was never found, and the clown costume was never recovered. But the guilty plea brought a measure of closure to a case that had haunted Wellington for decades.
Sheila Keen-Warren, now 59, will spend at least a few years behind bars, but many believe justice was not fully served. The question remains: did Sheila confess because she was truly guilty, or was she simply looking for a deal to cut her sentence? The answer, like the clown’s identity, may never be fully known.
The community of Wellington, which once prided itself on being a safe haven from the crime of nearby cities, was forever changed by the murder. The case served as a stark reminder that evil can wear any mask, even a clown’s. As Sheila begins her sentence, the Warren family continues to mourn a mother and wife taken too soon, while the rest of the world looks back on a case that defied belief until the very end.
