Tennessee tried to put Christa Pike to death on Wednesday night. She got two doses of a deadly drug. She did not die.

Pike, 50, was still breathing and snoring loudly, her lawyers said. An ambulance took her out of the prison. On Thursday, her lawyers said she was in critical condition at a hospital.

"Christa is alive right now," said Randy Spivey, one of her lawyers. "We don't have a sense of her prognosis or much update on her health at the moment, but we do know that she is alive right now and receiving life-saving medical care."

Pike is the only woman on death row in Tennessee. She was set to be the first woman the state put to death in more than 200 years.

Now the governor has hit pause. Gov. Bill Lee ordered "a comprehensive, third-party review to determine exactly what occurred." He also said the one other execution set for this year will not happen.

"There is no one that wanted what happened last night to happen. It shouldn't have happened," Lee told reporters on Thursday.

The state prison system said it "followed every step of the State's lawful, established execution protocol approved by the Attorney General's Office."

That plan calls for a second set of drug shots "if the inmate is not deceased" after the first set. It does not say what to do if the person is still alive after the second set.

Robin M. Maher leads the Death Penalty Information Center. She called what happened to Pike "singular and unparalleled." She said seven other people have lived through failed executions. In those cases, workers could not find a vein to put in the drugs. But no one has stayed alive after getting the drugs, she said.

Here is how the night went, according to witnesses. The curtain opened at 7:27 p.m. Pike was strapped to a gurney, a bed on wheels.

"I'm going to leave this world the way I spent most of my life and that is in love," she said.

Pike stayed awake. At one point she lifted her head. She asked if her arm was supposed to feel that way. Witnesses said the second dose was in by 8:26 p.m. Pike could still be heard snoring behind the closed curtain. The microphone was cut at 8:53 p.m.

Spivey said workers spent about an hour trying to get an IV line in. He said he counted at least seven needles in her left arm. Her lawyers said they had warned the state about her blood problems months ago.

"Last night was not just inefficient. It was cruel, and it was torturous," Spivey said. "It was also predictable."

Her lawyers now want the governor to change her sentence to something less than death. "The governor must commute Christa's sentence now," Spivey said.

The fight in court went on all day. Pike was set to die at 10 a.m. local time. About an hour before, a federal appeals court stopped it. Pike says she was abused as a child. That court wanted to see if that was fully weighed when she was sentenced. The state took it to the U.S. Supreme Court. Hours later, the high court let the execution go ahead. Three justices disagreed.

This is the second failed execution in Tennessee this year. In May, the state called off the execution of Tony Carruthers. Workers tried for more than an hour to get an IV in and could not.

Pike was 18 when she killed Colleen Slemmer on January 12, 1995. Slemmer was 19. The two were classmates at a job training center in Knoxville. Prosecutors said Pike lured Slemmer to a wooded area. They said Pike cut her with a box cutter and beat her with a big chunk of asphalt.

Pike's boyfriend, Tadaryl Shipp, was 17 at the time. He got life in prison with a chance at parole. Pike was the only one sentenced to death.

Pike did not deny the killing. Her supporters asked the state to think about how young she was. They also pointed to her mental illness and the abuse she says she suffered.

Slemmer's mother, May Martinez, had come to Nashville to watch the execution. She said she had waited decades for it.

"Every time I think about it, I think about Colleen feeling that pain and trying to get up and run," Martinez said on Saturday, days before.

It is not clear what comes next. Pike's lawyers said the state does not have to ask for a new date. They said the electric chair is still an option under state law. For now, Pike is in a hospital. The governor said Tennessee will not carry out any more executions this year.
