US Senator Marsha Blackburn has demanded wider use of Tennessee's electric chair after convicted murderer Christa Pike, 50, survived two doses of pentobarbital during a failed execution, and was left in critical condition.
The attempted execution took place on Wednesday at Riverbend Maximum Security Institution in Nashville, where Pike was to be put to death for the 1995 murder of 19-year-old Colleen Slemmer, her attorneys said.
