A lone robber held up the Maverik Country Store in Ririe late Monday night.
Jefferson County Sheriff Blair Olsen said the man entered the store around at 11:20 p.m. and told the clerk he had a gun. A gun was never actually displayed. He escaped with an undisclosed amount of cash. No one else was in the store.
The bandit was described as about 6 feet tall with a heavy build. He was wearing a gray overcoat with a hood, dark jeans, light gloves and a skull mask.
