Lawyers for Christa Pike warned months before Tennessee attempted to execute her that her medical conditions and difficult-to-access veins could make lethal injection especially dangerous, arguing that the state’s execution protocol risked subjecting her to excruciating pain.

Pike, 50, survived two doses of pentobarbital during a Sept. 30 execution attempt and was taken to a Nashville-area hospital. She regained consciousness and began walking again last week.
