Christa Pike, a US death row inmate, is "conscious and speaking" after surviving a failed execution attempt last week, her lawyers say.
Pike, 50, continues to receive intensive medical care while being held in handcuffs at the hospital, her lawyers said in a statement Tuesday.
Pike, who was sentenced to death for killing Colleen Slemmer in 1995, survived two failed attempts at lethal injection last Wednesday in Tennessee.
She was taken to the hospital, where she remained unconscious for several days while medical personnel worked to cleanse her body of the injected chemical substance.
Experts and her legal team say her recovery is unprecedented. She is believed to be the only person to have survived a lethal injection.
Her lawyers described her progress as "medically unprecedented" and, while the prognosis remains unclear, "at the very least, we expect a long recovery."
Deborah Denno, a criminologist and lecturer at Fordham Law School, said she was "completely surprised" that Pike is conscious and speaking out.
There were seven other cases where prisoners survived after scheduled executions, but in those cases, the executioners failed to inject anything into the prisoners' veins, Denno told the BBC.
Pike "is the only human who has been injected with some kind of toxin," she said.
“They did everything they were supposed to do as part of the execution process and it just didn’t work,” Denno said. “This has never happened before.”
What happened during Christa Pike's failed execution – and what's next?
Authorities have not yet stated whether they will try to execute Pike again.
They also did not explain what went wrong after injecting her with the chemical pentobarbital.
Tennessee Governor Bill Lee suspended all executions for the rest of the year, while the head of the state's prison system announced over the weekend that he plans to resign.
Pike was 18 when she and her then-boyfriend, Tadaryl Shipp, beat, tortured and killed 19-year-old Slemmer, whom they had met at a vocational training camp for youth with behavioral problems.
Pike's lawyers are expected to appear in court in Nashville on Wednesday. They also plan to hold a news conference outside the courthouse.
