Stephen Stanko, a South Carolina death row inmate, chose lethal injection over firing squad after witnessing complications from a recent execution where the inmate suffered before dying. Stanko, convicted of two murders, was informed that lethal injection could feel like drowning, but state medical experts asserted it would cause no pain. South Carolina recently resumed executions after a long hiatus due to drug shortages, and Stanko’s execution is scheduled for June 13.
