A Palm Beach County Sheriff’s Office news release says 54-year-old Sheila Keen Warren was arrested Tuesday in Virginia. A Florida grand jury recently indicted her on a first-degree murder charge.
Authorities say Marlene Warren was shot at her Wellington home in May 1990. Sheila Keen was considered a suspect but was not arrested.
Palm Beach County deputies reopened the case in 2014 and conducted a new DNA analysis. Detectives also learned that Sheila Keen married Marlene Warren’s widower, Michael Warren, in 2002. The couple had been living in Tennessee.
Detectives haven’t said whether Michael Warren was involved in his former wife’s death.
It wasn’t known if Sheila Keen Warren has an attorney.
