Prison officials in Arizona have denied inmate Joseph Rudolph Wood was in pain during execution yesterday afternoon.
Wood gasped for around 90 minutes during his execution and eventually died almost two hours after the lethal drugs where administrated. His lawyers filed an emergency appeal while the execution was ongoing.
State Departments of Corrections Director Charles Ryan said he was assured "unequivocally" that Mr Wood was aware of what was happening, or in any pain.
Throughout this execution, I conferred and collaborated with our IV team members and was assured unequivocally that the inmate was comatose and never in pain or distress.
