US death row inmate Christa Pike is conscious and speaking after a failed execution attempt last week in Tennessee, her lawyers announced Tuesday. The 50-year-old remains under critical medical care in a hospital, handcuffed and shackled to her bed, according to a statement from her legal team.

Pike was sentenced to death in 1995 for the murder of 19-year-old Colleen Slemmer, whom she killed with her then-boyfriend. The execution attempt, involving two lethal injections, was carried out last Wednesday in Tennessee. Pike was subsequently taken to a hospital, where she remained unconscious for several days as medical staff worked to clear the chemical from her system.

Experts and Pike's legal team describe her apparent recovery as unprecedented. Criminologist and Fordham Law School professor Deborah Denno expressed astonishment at Pike being conscious and speaking, noting that while seven other prisoners have survived executions, in those instances, the executioners were unable to administer any substances. "Pike is the only person for whom some kind of toxin has been injected," Denno told the BBC, adding that "They did everything they were supposed to do as part of the execution process, and it simply didn't work."

Authorities have not yet indicated whether they will attempt to execute Pike again or provided an explanation for the failure of the lethal injection protocol using pentobarbital. Tennessee Governor Bill Lee has suspended all executions in the state for the remainder of the year. The head of the state's prison system also announced plans to resign over the weekend.

Pike, who was 18 at the time of the murder, along with her then-boyfriend Tadaryl Shipp, tortured and killed Slemmer. Shipp, who was 17, was not eligible for the death penalty due to his age. He remains incarcerated.

Pike's lawyers are scheduled to appear in court in Nashville on Wednesday and plan to hold a press conference. They have reiterated their plea for Governor Lee to commute Pike's sentence to life imprisonment without parole.

Dr. Joel Zivot, an anesthesiologist advising Pike's defense, stated on Tuesday that Pike's prognosis remains uncertain but that her legal team anticipates a lengthy recovery period. The case has raised significant questions, including the emotional impact on the victim's family, who have waited three decades for justice.

A local journalist who witnessed the botched execution confirmed that there is no known exact precedent for such an event. The incident highlights ongoing controversies and challenges surrounding the administration of lethal injections and the death penalty process.
