Tennessee halts executions after Christa Pike survives 2 doses of lethal drug. Tennessee officials were unable to put Christa Pike to death on Wednesday for a 1995 murder after administering two doses of a lethal drug. A death penalty expert said it was an unprecedented failure, and Tennessee’s governor halted the remaining execution for the rest of the year. Pike, 50, was alive and loudly snoring after the attempted lethal injection and taken by ambulance.
