Aiken Department of Public Safety charged Shaun Andrew Benson, 26, of the 2800 block of Sunshine Lane in Thomson, with armed robbery, Lt. David Turno said in a news release.
His father notified the department Tuesday night when he recognized his son in surveillance photos in the news media, Lt. Turno said.
Mr. Bensons father made arrangements for him to turn himself at the department this morning.
Around 5 a.m. Tuesday, authorities believe Mr. Benson entered the Kangaroo Express on Whiskey Road, put a screwdriver up to the clerks neck and demanded money, Lt. Turno said. The victim said she gave the suspect money, and he ran from the store toward Advanced Auto Parts.
Mr. Benson is being held at the Aiken County Detention Center.
