NASHVILLE, Tenn. (AP) — The Tennessee Supreme Court on Tuesday set execution dates for four people, including the only woman in the state on death row.

Christa Pike received the death sentence at age 18 for the 1995 torture slaying of Colleen Slemmer, who was a fellow Knoxville Job Corps student. Slemmer, 18, was stabbed and beaten by Pike and Tadaryl Shipp, Pike’s boyfriend at the time, on the University of Tennessee’s Agricultural campus.

They carved a pentagram into Slemmer’s chest, and investigators claimed Pike took a piece of the victim’s skull for a souvenir. Shipp, of Memphis, was sentenced to life in prison with the possibility of parole. Pike was also convicted in 2004 for trying to strangle a fellow inmate during a prison fight, which added 25 years to her sentence.

Pike’s attorneys previously asked the state’s high court to commute her sentence based on her youth and “severe mental illness at the time of her crime.”

Pike suffered physical and sexual abuse and neglect as a child, according to her attorneys. She also suffered from bipolar and post-traumatic stress disorders that were not diagnosed until years after her arrest.

“With time and treatment … Christa has become a thoughtful woman with deep remorse for her crime,” a Wednesday statement from her attorneys reads.

Tennessee began a new round of executions in May after a three-year pause following the discovery that the state was not properly testing lethal injection drugs for purity and potency.

An independent review later found that none of the drugs prepared for the seven inmates executed in Tennessee since 2018 had been fully tested. The state Attorney General’s Office also conceded in court that two of the people most responsible for overseeing Tennessee’s lethal injection drugs ” incorrectly testified ” under oath that officials were testing the chemicals as required.
