I've seen nearly 500 executions - but never one like Christa Pike's

Journalist Michael Graczyk, who has covered nearly 500 executions in Texas, witnessed an unusual case in Tennessee where inmate Christa Pike, aged 50, remained breathing and snoring after two doses of pentobarbital. Tennessee's protocol includes a second set of injections if the first fails, but Pike survived, marking a rare occurrence. She is now in hospital receiving life-saving care, and Tennessee's governor Bill Lee has halted executions pending an independent review. The incident raises concerns about the reliability of lethal injection procedures in the US.
