SundanceTV revisits a bizarre cold case this Thursday with The Killer Clown: Murder on the Doorstep, airing at 10 PM ET. The true-crime documentary unravels the twisted tale of Marlene Warren’s murder—a case that initially baffled investigators but ultimately saw a resolution thanks to advancements in DNA technology.
The investigation kicks off with an affair—Marlene’s husband, Michael, having stepped outside the marriage with a woman named Sheila. The trail leads to Sheila, further solidified by a store clerk who identifies her as having bought a distinctive clown costume similar to the one worn by Marlene’s killer. But without hard proof, the investigation stalls, the case growing colder with each passing year.
The turning point arrives in 2017 when new DNA testing breaks the decades-long stalemate, finally giving detectives the evidence they need to make an arrest. The Killer Clown doesn’t just recount the facts; it breaks down the science behind the breakthrough, showing how forensic advancements can bring closure to seemingly unsolvable crimes.
The Killer Clown: Murder on the Doorstep premieres Thursday, June 12th at 10:00 PM ET on SundanceTV.
