Christa Gail Pike, 50, was taken by ambulance from the prison, her attorneys said.

Pike, 50, was alive and loudly snoring after the attempted lethal injection and taken by ambulance from the prison, her attorneys said. She was being treated at a hospital, but they said they hadn’t been told about her condition.

She had been scheduled for execution at 10 a.m. Wednesday for the killing she committed at age 18 and would have been the first woman executed in Tennessee in more than 200 years. An appeals court stopped the lethal injection just an hour before it was to start and hours later the US Supreme Court overturned that stay.

Media witnesses observing from a separate room said officials raised curtains to the execution chamber at 7:27 p.m., showing Pike strapped to a gurney.

“I’m going to leave this world the way I spent most of my life and that is in love,” she said in her “last” words. She described herself as at peace.

Pike continued to be heard snoring behind the closed curtain until the microphone was cut off at 8:53 p.m. At that time there was an announcement to escort media witnesses out of the area.

Pike and her boyfriend were convicted of the fatal stabbing and beating in 1995 of 19-year-old Colleen Slemmer, their classmate at a job training facility in Knoxville. The case garnered widespread attention in part because of 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.

Later in the day, the high court cleared the way for the execution to proceed. The conservative majority did not explain their order, while the three liberal members signed a dissent that said Pike’s claims deserved a closer look.

Pike did not deny committing the killing, but her supporters argued that the state should consider her age at the time, her mental illness and her allegations of severe sexual abuse.

As the execution date drew near, debate renewed over the death penalty for young offenders. 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,” Pike said in a statement.

Slemmer’s mother had traveled to Nashville in the hopes of witnessing the execution of her daughter’s killer. She told the Associated Press on Saturday that she had waited decades to see Pike’s sentence carried out.

Pike would have been the 30th person executed in the US this year after Florida carried out an execution on Tuesday.

Tennessee announced in 2024 that it was switching from a three-drug series for lethal injections to the single drug pentobarbital. That came more than two years after the state abruptly halted the execution of Oscar Smith and acknowledged that it had failed to ensure its lethal injection drugs were tested properly.

This story has been updated to correct that Pike had been scheduled for execution at 10 a.m. local time, not 11 a.m., and that the lawyers filed an emergency motion to the Tennessee Supreme Court, not US.
