Death row killer Christa Pike, who survived a botched Tennessee execution, says she is in constant pain and blames 'incompetence'

Death row inmate Christa Pike, 50, dictated a lengthy statement to her legal team one month after surviving two lethal injections of pentobarbital on 30 September at Riverbend Maximum Security Institution in Tennessee — the only person believed to have survived execution by lethal injection. She said she walked into the chamber "prepared to die" and had made her peace, never imagining she would need to contemplate life beyond that night.

Faulty IV lines are believed to have sent the drug into Pike's arm tissue rather than her bloodstream, leaving both arms swollen, burned and blistered.

Victim Colleen Slemmer's mother, May Martinez, watched the botched procedure and told reporters: 'All I wanted was justice' — and says Tennessee owes her an apology.

Pike remains isolated in the prison infirmary, still unable to swallow properly; Tennessee Governor Bill Lee has ordered an investigation and postponed the state's other scheduled execution.
