Christa Pike remains critically ill and is on a ventilator at a Nashville-area hospital two days after Tennessee failed to execute her by lethal injection, according to her attorneys.

Pike’s attorneys said Friday that she is unconscious, intubated, and receiving medical treatment after surviving Wednesday’s execution attempt. They filed a request seeking an order requiring the Tennessee Department of Correction to preserve evidence connected to what they described as the state’s failed attempt to execute her.

According to the filing, the execution team used at least seven needles while attempting to establish intravenous access. Pike’s attorneys said one needle was removed from her body bent at roughly a 90-degree angle.

The filing also says Pike could be heard crying, whimpering, and breathing heavily during the procedure. At one point, she reportedly told officials that her arm felt as though it was about to burst and asked whether the experience was normal.

Pike’s lawyers had previously warned Tennessee officials that she had a blood condition that could make the lethal injection process more difficult. They also said she had a history of medical professionals having difficulty locating her veins and establishing IV access.

Her attorneys said both of Pike’s arms were swollen, burned, and blistered when she arrived at the hospital. They allege the IV lines were improperly placed or that the veins had blown, allowing pentobarbital to leak into surrounding tissue.

The attorneys further allege that the execution team did not recognize or correct the problem before administering a second dose of pentobarbital. Hospital personnel are now treating Pike and working to clear the drug from her system, according to her lawyers.

Tennessee officials have maintained that the Department of Correction followed the state’s established execution protocol. The department said after Wednesday’s attempt that Pike was transported to an off-site medical facility.

The failed execution has also prompted Tennessee Gov. Bill Lee to halt the state’s remaining scheduled executions for the rest of the year while ordering a comprehensive, third-party review of what occurred.

Pike’s attorneys have called for her death sentence to be commuted following the failed execution. The request comes as state officials investigate the circumstances surrounding the attempt.

Pike was sentenced to death for the 1995 murder of Colleen Slemmer, whom she met while both were students at a Job Corps Center in Knoxville. Pike was 18 at the time of the killing and is now 50.

She had been scheduled to become the first woman executed in Tennessee in roughly two centuries. The Supreme Court allowed the execution to proceed earlier Wednesday, before the lethal injection attempt failed.
