Death row inmate Christa Pike has regained consciousness after Tennessee’s failed attempt to execute her by lethal injection last week, and her attorneys are set to head to court to seek more information about what went wrong.

Pike, 50, survived two doses of pentobarbital as executioners attempted to put her to death September 30 for the 1995 beating and stabbing death of classmate Colleen Slemmer. Pike is believed to be the only person to survive lethal injection.
