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.

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.

A South Carolina man convicted of murder is set to be put to death by lethal injection on Friday, the first execution in the US this year.
