Security images have been released of the two masked gunmen who held up the Conoco convenience store on Stevens Drive in Richland Tuesday night.

Around 10:20pm the two men entered, wearing dark grey and black hoodies, masks and displayed a gun. They were seen leaving in a yellow Mustang, probably a 1995 or similar model. Some say 1998 to 2004.

Based upon images and the clerk description, both were about 6 feet tall, average build, and one suspect wearing a turquoise green mask or other covering. Anyone with any information is asked to call (509)-628-0333. All leads can be confidential.
