Sheila Warren returned to Palm Beach County late Tuesday night, 27 years after investigators claim she fatally shot a woman whose husband would eventually become her own.
Warren was escorted into jail, one week after her arrest in Washington County, Virginia. She is charged with first-degree murder in the May 26, 1990, shooting of Marlene Warren.
Palm Beach County Sheriff's Office Detective Paige McCann said Sheila Warren was dressed like a clown when she killed the woman at her Wellington home.
"Marlene answered the front door and the clown had two balloons, as well as a bouquet of flowers, and went to hand Marlene those items," McCann told reporters last week.
The Wellington woman, who had been eating breakfast with her then-22-year-old son and several of his friends, was surprised and commented, "How nice."
"It was at that time that the clown pulled out a gun and shot Marlene in the face," McCann said.
The clown then calmly walked back to the white Chrysler LeBaron in which she had arrived and drove away.
Marlene Warren died at a hospital two days later.
Investigators had long considered Sheila Warren to be a suspect in the shooting, but they spent 27 years building their case.
McCann said it had been rumored that Sheila Warren and the victim's husband were having an affair.
Sheila Warren -- 26 at the time and then known as Sheila Keen -- eventually married Michael Warren in 2002 and the couple moved to Tennessee, where they operated a restaurant.
A Palm Beach County grand jury was presented the evidence in August and returned an indictment against Sheila Warren, leading to her arrest.
Sheila Warren could face the death penalty.
