NASHVILLE, Tenn. — Tennessee's execution of Christa Gail Pike for a murder she committed at age 18 was halted Wednesday about an hour before it was set to begin, as a federal appeals court sought to review whether her allegations of childhood sexual abuse and rape were fully considered at her sentencing.
Pike, now 50, and her boyfriend were convicted of the 1995 stabbing and beating of 19-year-old Colleen Slemmer, their classmate at a job training facility in Knoxville. She would have been the first woman executed in Tennessee in at least 200 years.
The 6th Circuit U.S. Court of Appeals halted the execution on a 2-1 vote after execution witnesses and others gathered at the Riverbend Maximum Security Institution in Nashville.
Tennessee’s attorney general immediately appealed the stay to the U.S. Supreme Court. Witnesses and media remained at the prison in case the high court allows the execution to proceed. Media witnesses were brought into the prison about 10:15 a.m. to wait.
More than 30 people, some wearing shirts that said “Love Heals,” gathered in a fenced-in area outside the prison while police on horses watched nearby.
The case garnered widespread attention at the time of the killing in part because a pentagram that was carved on Slemmer’s body and other elements of the crime stoked fears of Satan worship during the “satanic panic” of the 1980s and 1990s.
Pike's case renewed debate on the death penalty for teens
As the execution date drew near, it renewed debate over the death penalty for young offenders.
Pike does not deny committing the killing, but her supporters argue the state should consider Pike’s age at the time, mental illness and a history of severe sexual abuse that included being raped from the time she was a toddler. Assistant Federal Defender Stephen Ferrell said Pike’s death sentence is an outlier because other 18-year-olds in Tennessee have had such sentences vacated.
After the killing, Pike was diagnosed with bipolar disorder and post-traumatic stress disorder. In her clemency petition she said she only wanted to fight Slemmer but killed her in a frenzied attack when she couldn’t “put the brakes on.”
“I was a mentally ill 18-year-old kid. It took me numerous years to even realize the gravity of what I’d done. Even more to accept how many lives I affected. I took the life of someone’s child, sister, friend. It sickens me now to think I had the ability to commit such a crime,” Pike said in a statement.
Victim's mother says she is waiting for death sentence
Slemmer's mother wants the lethal injection to go forward, saying she has waited decades to see Pike's sentence carried out.
“Every time I think about it, I think about Colleen feeling that pain and trying to get up and run,” May Martinez told The Associated Press in a telephone interview on Saturday.
Martinez said a group helped raise money so she and her husband could travel from Florida to witness the execution.
Martinez said her daughter's age should matter too in deciding Pike's fate.
“Not a day goes by, or a minute goes by that I do not think about Colleen. Holidays are the worst,” she said, noting that her daughter would have turned 51 earlier in September.
The killing rocked the city of Knoxville. Prosecutors said Pike, fearing Slemmer was trying to steal her boyfriend, lured her to a wooded area on Jan. 12, 1995. Pike cut Slemmer with a box cutter and beat her with a large chunk of asphalt. Shipp, Pike’s boyfriend, has admitted that he was the one who carved a pentagram, a star-shaped symbol associated with Satan, into her body.
Shipp was 17 when the crime happened and received a sentence of life in prison with the possibility of parole. Pike was the only one sentenced to death.
Executions of women are rare in the US
Tennessee has not executed a woman for at least 200 years, according to Robin M. Maher, executive director of the Death Penalty Information Center. Older records can be spotty, though, so it’s difficult to know precise details about the last woman who was put to death there.
It's a rarity across the U.S. Since 1976, 18 women have been put to death in the country, representing about 1% of all executions, according to the center.
Most recently, Missouri in 2023 executed Amber McLaughlin for a 2003 killing, in what is believed to be the first execution of a transgender woman in the U.S. In 2021, the federal government executed Lisa Montgomery, marking the first time in nearly seven decades that the U.S. government put a female inmate to death.
Pike would be the 30th person executed in the U.S. this year. Florida carried out its 16th execution of 2026 on Tuesday.
