The South Carolina House on Wednesday passed a bill to add firing squad as a state execution method.
South Carolina has gone out of appeal with three deadly row inmates as lethal injection injected as the measure passed.
If the state has drugs, lethal injection will remain the primary execution method under the bill. But if they are out, prisoners with capital punishment must either be shot or electrocuted.
The state Senate had already passed the bill in March. Government Henry McMaster should still sign the legislation, which he has vowed to do.
South Carolina will become the fourth state to allow a firing squad. Currently, it is one of nine that use an electric chair in execution.
A death sentence inmate was given the death penalty 10 years ago in the state.
According to the Death Penalty Information Center, Mississippi, Oklahoma and Utah currently allow firing squads for execution.
Since the US reinstated the death penalty in 1977, all three prisoners in Utah were killed by firing squad.
