An overnight robbery is being investigated by the Shasta County Sheriff’s Office. At around 3AM the 4th Street Chevron in Cottonwood was held up at gunpoint by a white or hispanic male in his 20’s or 30’s, average height and build, with tattoos on his right hand and his face. He was wearing a mask, a black hoodie, and baggy gray shorts. The cashier told deputies the robber was favoring his right arm as if he had a shoulder injury. He fled in a light colored sedan with money, food and medications.
