The Richland County Sheriff's Department said Wednesday that 49-year-old Ervan Matthew Harvey was arrested and charged with murder and strong-armed robbery.
Deputies say Charles Duaine Hamilton died when he confronted three men at a Sears store in August 2017 and was shoved to a concrete floor, causing a head injury that later killed him.
The sheriff's department said Harvey and Jeffrey Alan Simmons and Jason Randolph were stealing two televisions when they were confronted by Hamilton, who was working as a loss prevention officer.
Simmons and Randolph were arrested last year.
It was not known if Harvey has an attorney.
