prison

In 1977, death row inmate Gary Mark Gilmore chose to be executed by a firing squad. Gilmore was strapped to a chair at the Utah State Prison, and five officers shot him.

The media circus that ensued prompted a group of lawmakers in nearby Oklahoma to wonder if there might be a better way to handle executions. They approached Dr. Jay Chapman, the state medical examiner at the time, who proposed using three drugs, based loosely on anesthesia procedures at the time: one drug to knock out the inmates, one to relax or paralyze them, and a final drug that would stop their hearts.
