PALM BEACH COUNTY, Fla. — Details emerged Thursday about a woman arrested in a 1990 “killer clown” Florida cold case slaying – and her relationship with the victim’s husband, who she later married.
The Palm Beach County Sheriff’s Office says 54-year-old Sheila Keen Warren wasA Florida grand jury recently indicted her on a first-degree murder charge. Police have long suspected Keen Warren of being the person who in May 1990 dressed up as a clown, knocked on the door of a Wellington, Fla. home carrying flowers and balloons, and shot dead the woman who answered the door, Marlene Warren.
But officials say they didn’t have enough evidence to charge Keen Warren in the case until now. A detective said the sheriff’s office in 2014 received a grant and had been reviewing a number of unsolved murders, including Marlene Warren’s. It was recent advancements in DNA technology that allowed for the break in the case, but detectives Thursday wouldn’t detail where the DNA was found or how they linked it to Keen Warren.
Without the new evidence, they likely would not have been able to convince a jury of Keen Warren’s guilt, they said.
“You basically get one shot and if you roll the dice and take that chance and she is found not guilty, you never get that chance again,” said Sheriff’s Detective Paige McCann, who headed the investigation. “Sometimes patience is the best.”
The detectives who were giving the case a fresh look also learned that in 2002, Keen Warren had married the victim’s husband, Michael Warren. A cold case detective said several witnesses told police that Keen Warren – then Sheila Keen – and Michael Warren were having an affair. Both, however, have denied that they were romantically involved at the time of the 1990 murder.
Michael Warren reportedly owned Bargain Motors, a West Palm Beach auto dealership, and the suspect worked for him repossessing cars. The Sun Sentinel reports the two, both married to others, often took long lunches. The suspect separated from her first husband Richard Keen in January 1990 after a three-year marriage, the paper reports. After that, Michael Warren reportedly paid her rent.
After the slaying, detectives say, they found evidence pointing to the then Sheila Keen, but not enough to charge her. Costume…
