Three masked men robbed the Dairy Queen on Lady's Island at gunpoint just before 11 p.m. Friday, according to the Beaufort County Sheriff's Office.
The men entered through a back door and demanded cash, according to a news release, which did not say how many of the suspects were armed. After being given an undisclosed amount of money, all three fled the store, leaving employees unharmed.
A search yielded no suspects, but deputies found evidence suggesting they drove off in a vehicle parked on a dirt driveway on nearby Miller Drive.
The suspects are all described as black men, 18 to 30, wearing masks and dark clothing.
Anyone with information should call Investigator Sgt. J. Kelleher at 843-255-3418 or county dispatch at 843-524-2777.
