South Carolina is preparing to execute the third inmate to be put to death since September as the state goes through a backlog of prisoners who exhausted their appeals while the state couldn’t find lethal injection drugs.

Bowman’s execution was the third carried out in South Carolina since 2011, when the state unofficially halted executions as pharmaceutical companies stopped supplying lethal injection drugs, fearing public concern over suffering of those executed.

An inmate on South Carolina’s death row died by lethal injection on Friday night, the third execution carried out by the state since reinstating capital punishment.
