An unknown, masked suspect robbed Pruitt's Grocery store in downtown Beaufort at gunpoint Saturday and fled with an undetermined amount of money, according to the Beaufort Police Department. The subject, described as a tall, thin black man wearing a mask, entered the businesses at about 7:50 p.m. and demanded money from the clerk, police Chief Matt Clancy said in an e-mail. The clerk fell or was pushed down by the subject and was examined by Beaufort County Emergency Medical Services at the scene, Clancy wrote. The Beaufort County Sheriff's Office K-9 unit was dispatched but did not find the subject, Clancy said. The investigation continues, and anyone with information is asked to call 843-322-7958 or dispatch at 843-524-2777.
