WASHINGTON, United States (AFP) — The convicted murderer who survived a botched execution attempt in the United States (US) state of Tennessee last week has been discharged from hospital and returned to prison, her lawyers said Saturday.

Christa Pike, 50, was administered two lethal doses of the drug pentobarbital on September 30 that failed to kill her.

She was transported to hospital in critical condition but later regained consciousness, with her lawyers saying this week that she was walking around but in a “foggy” mental state.

“Christa Pike was discharged from a local hospital and is now at Deborah K. Johnson Rehabilitation Center where she has been housed for more than 30 years,” her lawyers said in a statement Saturday.

Pike was sentenced to death in Tennessee for murdering a classmate, a crime committed when she was a teenager.

“She is grateful to the first responders and her medical team for their care in these extraordinary circumstances,” the statement went on.

Pike “is continuing to receive medical care at the prison, and we will continue to track her recovery,” the lawyers said.

The attempted execution came after days of last-minute legal wrangling that ultimately reached the Supreme Court.

Pike’s legal team had previously objected to the execution IV protocol, saying it would have caused needless suffering due to her small veins and a blood condition.

Since the botched execution, her lawyers have repeatedly called on Governor Bill Lee to commute her sentence to life in prison.

Lee has suspended executions in Tennessee pending an independent investigation.

Pike’s stunning survival renewed focus on the ethical debate surrounding capital punishment in the United States.

That debate has intensified following the Pentagon’s announcement this week that it intends to livestream an execution by firing squad later this year.

The move has prompted outrage from a broad array of public figures in the United States, including many Republicans supportive of the death penalty.

Pope Leo, the first American pontiff, posted Saturday on X that “the death penalty is inadmissible because it is an attack on the inviolability and dignity of the person.”

“The common good can be safeguarded and the requirements of justice can be met without recourse to capital punishment,” he said.

The death penalty has been abolished in 23 of the 50 US states, while three others — California, Oregon and Pennsylvania — have moratoriums in place.

The federal government instituted a moratorium under president Joe Biden, but President Donald Trump’s administration lifted it when he returned to office in 2025.
