911 calls show 30-minute delay after Christa Pike's botched execution

Newly released 911 calls reveal confusion that delayed emergency help after Tennessee's attempted execution of Christa Pike, convicted of killing Colleen Slemmer. Two doses of pentobarbital failed to kill her. The first 911 call came at 8:40 p.m., but it took about 30 minutes for officials to verify the call was legitimate. Pike's attorney called 911 saying she was still alive and needed immediate care. She was hospitalized, then returned to prison.
