A sketch has been released by Tehama County Sheriff's Detectives in hopes of catching a bank robber. At 10:40AM last Thursday morning a man walked into the Umpqua Bank in Los Molinos and brandished a semi-auto handgun to the teller, demanding money. He was given an undisclosed amount of cash and he left on foot. He was apparently not seen getting into any vehicle. The teller hit the silent holdup alarm, but by the time deputies arrived the robber was gone. He's described as a white man between 30 and 40 years old, 6-Foot-2, about 200 pounds, with a medium build. He had short dark hair and was wearing a black ballcap with a San Francisco Giants "SF" logo. He also wore bluejeans, a black jacket, and dark high-top basketball or skater shoes. To try and conceal his identity he wore dark wrap-around sunglasses and a white dust mask. The FBI is assisting in the investigation.
