May 26, 1990 — Wellington, Florida. 40-year-old Marlene Warren was at home having breakfast with her son when a car pulled into the driveway. A person dressed as a clown — holding flowers and two balloons — walked to her door.
She smiled and accepted the gifts.
Seconds later, the clown pulled out a g*n and sh*t her in the face before calmly walking away. She was rushed to the hospital but died two days later.
The case quickly turned bizarre. Witnesses saw the clown leave in a vehicle, and investigators soon focused on Sheila Keen, a woman connected to Marlene’s husband, Michael Warren.
At the time, authorities suspected there may have been a romantic relationship between Sheila and Michael, though both denied it.
But despite early suspicion — including witnesses linking her to a clown costume and balloons — there wasn’t enough evidence to arrest her, and the case went cold.
More than a decade after the m**der, in 2002, Sheila Keen married Michael Warren — the victim’s husband.
For years, they lived a new life together while the case remained unsolved.
In 2017, advances in DNA testing linked Sheila to evidence from the suspected getaway car, leading to her arrest nearly 27 years later.
Investigators believe the k**ling was driven by a personal relationship, jealousy, and financial motives tied to the marriage.
In 2023, Sheila Keen-Warren pleaded guilty to second-degree m**der, bringing an end to one of the most unusual cold cases in the U.S.
Marlene Warren is remembered as a mother whose life was taken in a moment that still feels unreal — a reminder that sometimes, the most unexpected knock can be the most dangerous.
