Mississippi lawmakers are advancing a proposal to add firing squad, electrocution and gas chamber as execution methods in case a court blocks the use of lethal injection drugs.
The firing squad execution chamber at the Utah State Prison after Ronnie Lee Gardner was executed on June 18, 2010.
Lethal injection is Mississippi's only execution method. The state faces lawsuits claiming the drugs it plans to use would violate constitutional prohibitions against cruel and unusual punishment.
Mississippi hasn't been able to acquire the execution drugs it once used. Sources of these drugs are from other countries unwilling to continue supplying them.
The Death Penalty Information Center says of the 33 states with the death penalty, only Oklahoma and Utah have firing squad as an option.
