(March 24, 2023) - Idaho Governor Brad Little signed HB 186 to execute inmates by firing squad when lethal injection is unavailable
Idaho now joins Utah, South Carolina, Mississippi and Oklahoma that allow firing squads for death row inmates. Idaho has never executed a death row inmate by firing squad, and the method was later abolished in 2009.
Gerald Pizzuto was set to be executed last year -- but the Idaho Department of Corrections (IDOC) called it off due to lack of the drugs needed for the execution.
