Electrocution
After the first cycle of electricity was applied, and again four minutes later, prison physician David Barnes inspected Peterson's neck and checked him with a stethoscope, announcing each time "He has not expired." Seven and one-half minutes after the first attempt to kill the inmate, a second cycle of electricity was applied. Prison officials later announced that in the future they would routinely administer two cycles before checking for a heartbeat.
