Police are looking for a suspect after a Murphysboro convenience store was robbed early Wednesday morning.
Officers were called to the Moto Mart on South Williams Street just before 4:00 Wednesday morning, where the clerk told them a black man wearing a mask had held up a knife and demanded money.
The clerk gave the man an undisclosed amount of cash, and the suspect ran away. Police say he was headed south. Investigators are looking over surveillance video and processing other evidence in the case.
