In 1990, Marlene Warren opened her front door to find a clown holding flowers and balloons.

Seconds later, the clown pulled out a gun and shot her in the face.

The killer calmly walked back to a white Chrysler LeBaron and drove away — leaving behind one of the strangest murder mysteries in Florida history.

For more than 27 years, the identity of the person behind the clown makeup remained officially unresolved. But investigators had focused early on Sheila Keen, a woman suspected of having an affair with Marlene’s husband, Michael Warren.

Then the story became even more bizarre.

Years after Marlene’s murder, Sheila married Michael Warren.

In this episode of Santana True Crime: 31 Nights of Halloween, we break down the Marlene Warren “Killer Clown” murder, including:

🎈 The flowers and balloons used to approach Marlene
🤡 The mysterious clown costume
🚗 The white Chrysler LeBaron getaway car
🔎 Why investigators focused on Sheila Keen
💔 The alleged affair and possible motive
💍 Sheila eventually marrying Marlene’s husband
🧬 The forensic evidence that helped revive the cold case
⚖️ Sheila’s 2017 arrest and 2023 guilty plea
❓ And the question that remains: Did anyone else know what was going to happen?

This is a true story that sounds like a Halloween horror movie.
