PALM BEACH COUNTY, Fla. (Court TV) – An alleged ‘killer clown’ will stand trial for a cold case murder that happened 30 years ago.

 

Sheila Keen Warren is accused of shooting 40-year-old Marlene Warren on her doorstep in Wellington, Florida, on May 26, 1990. According to the Palm Beach County Sheriff’s Office, her 22-year-old son, Joseph Ahrens, and several of his friends were reportedly in the kitchen with Warren when they saw a white Chrysler LeBaron park in the driveway. A person dressed as a clown then exited the vehicle carrying a flower arrangement and balloons. When Warren answered the door, witnesses reportedly heard a gunshot before the suspect “calmly walked back to the LeBaron and drove away.” Warren died two days later. Her case ultimately went cold until 2014.

That year, investigators learned once-suspect Sheila Keen Warren had married Warren’s widow, Michael, in 2002. At the time of Marlene’s murder, Sheila reportedly worked for Michael. During their investigation, new DNA analysis reportedly linked Sheila Keen Warren to the murder, and three years later in 2017, she was arrested and charged with First Degree Murder.

Sheila Keen Warren was initially facing the death penalty, however, prosecutors announced they would not pursue it in February 2020, according to court documents.

Warren was supposed to go to trial on May 29, 2020, but it was postponed due to the COVID-19 pandemic.
