The Aiken County Sheriff's Office is investigating armed robbery incidents at separate Kent's Korner convenience stores in Aiken on Tuesday night.

In the first incident, Brandon Clifford Knight, 32, was detained after he allegedly robbed a convenience store of some beer, then returned to the store – as he promised earlier – to get cigarettes, according to Capt. Eric Abdullah, a spokesman for the Sheriff's Office.

Knight was charged with armed robbery and possession of a weapon during a violent crime. He was placed in the Aiken County detention center, where he remained on Wednesday afternoon.

The incident happened at 9:25 p.m. at the Kent's Korner on Wagener Road in Aiken, Abdullah said. Officers received a call from the clerk about a suspect who held him at knife point and stole some beer.

Sheriff's deputies responded and the clerk was able to give them a description of the suspect.

“The clerk informed deputies that the suspect left in an unknown vehicle and did threaten to return for cigarettes,” Abdullah said. “While sheriff's deputies were on scene, the suspect … did come back to the store where the clerk pointed him out to the deputies.”

Knight was arrested on scene, Abdullah said. He had been driven back to the store by another suspect, who investigators determined had no involvement in the robbery.

The Sheriff's Office is investigating a second armed robbery on Tuesday night during which a man was shot twice.

That incident happened just before 11 p.m. in the truck parking lot of Kent's Korner on Edgefield Highway near Interstate 20, according to Abdullah.

“Responding deputies met with the witness who told them that he and the victim were standing next to their vehicles when they were approached by a black male with a gun,” Abdullah said. “The witness told deputies that the suspect fired his weapon after the victim threw his coffee mug at him.”

The suspect fled the area before officers arrived on the scene. The victim was transported to Georgia Regents Medical Center. His condition was not known.

Anyone with information about this case is asked to call the Sheriff's Office at 803-648-6811, or CrimeStoppers of the Midlands at 888-CRIME-SC (888-274-6372).
