Sheila Keen-Warren

Sheila Keen-Warren is a villainess who murdered her lover's wife in 1990.

Sheila Keen worked with for Michael Warren as his car lot; her job was repossessing cars. At the time, Sheila (who was married) was having an affair with Michael, though both sides of the couple denied their relationship. Michael was also married to Marlene Warren, who Sheila saw as an an obstacle in her relationship with Michael.

On May 26, 1990, Sheila turned heel and shot Marlene to death, committing the murder while dressed in clown makeup. She drove up to Marlene's home and knocked on her door, after which Sheila shot and killed her perceived romantic rival. Regarding her costume, Sheila donned an orange wig, a red nose, and white makeup, while holding flowers, balloons, and her gun.

The case went cold for 27 years, and regarding Sheila, she married Michael after her divorce was finalized in 2002. The couple owned the Tennessee-based restaurant, The Purple Cow, though at some point in 2017, Sheila drunkenly boasted to an employee that shot and killed Michael's wife. After DNA evidence was found on the clown costume, Sheila was arrested in September 2017, and has since claimed that she didn't kill Marlene. Her trial is set to take place in February 2020.
