Christa Gail Pike survived two lethal injections and is unconscious on a ventilator

Christa Gail Pike, sentenced to death in the US state of Tennessee, is on a ventilator and remains unconscious after surviving two lethal injections, CNN reported, citing her lawyers.

WKRN previously reported that Christa Gayle Pike was in critical condition. Authorities have ordered a pause in executions in the state until the end of the year.

"Pike is on a ventilator and remains unconscious at a hospital in the Nashville area," CNN reported, citing her lawyers.

The execution was scheduled for Wednesday morning at the Riverbend maximum-security prison in Nashville, but the federal Sixth Circuit Court of Appeals blocked the proceedings an hour before it began to consider arguments about Pike's childhood abuse. A few hours later, the US Supreme Court, at the request of the prosecutor's office, canceled this reprieve, allowing the execution of the sentence.
