South Carolina executes second man by firing squad in 5 weeks

A firing squad on Friday executed a South Carolina man who killed an off-duty police officer, the second time the rare execution method has been used by the state in the past five weeks.

Mikal Mahdi cried out as the shots hit him, and his arms flexed. He groaned two more times about 45 seconds after that. His breaths continued for about 80 seconds before he appeared to take one final gasp.

The execution was performed by a three-person firing squad at 6:01 p.m. He was pronounced dead by a physician at 6:05 p.m., the South Carolina Department of Corrections confirmed to CBS News.
