Christa Pike is reported to be in critical condition after she survived the state of Tennessee's attempt to execute her. The execution, which should have resulted in her death by lethal injection, did not go as planned. Pike was sentenced to death for the 1995 murder of a fellow college student in Knoxville. She has spent decades on death row and has long been the only woman awaiting execution in the state. She is now being treated in hospital after the failed procedure. Officials have not yet explained in detail what went wrong during the process. Whether a new execution date will be set depends on how she recovers in the coming days.
