Death row inmate Christa Pike has been released from a US hospital and sent back to ‌prison where she will continue receiving medical care following her botched execution attempt ‌in Tennessee, her lawyers say.

Pike was discharged from a local hospital ‌on Saturday (local time).

She returned to the Debra K Johnson Rehabilitation Centre, where she has been housed for more than 30 years, her lawyers said.

Pike, sentenced to death for a 1995 murder, awoke “angry and confused” in the hospital last week facing a long recuperation after surviving the attempted execution on September 30, her lawyers said on Wednesday. They ⁠previously believed she could be brain-dead.

Pike, ‌50, ​had been taken from the execution chamber to a Nashville hospital, unconscious, ​critically ill ‌and with severe arm injuries after two injections failed to kill her ​at the Riverbend Maximum Security Institution.

A Tennessee judge has ordered state officials to preserve all evidence related to their failed ​attempt ​to execute Pike, a development ​one of her lawyers called the “first ‌of many steps to preserve and enforce her constitutional rights.”

Tennessee Governor Bill Lee suspended all executions in the state for the rest of the year while investigators look in to the botched execution of Pike and a similar ​failure involving Tony Carruthers in May, when prison officials were unable ​to set up intravenous ⁠lines.
