Glenn County authorities are looking for information in a July sexual assault investigation. The Glenn County Sheriff's Office says a woman thought she was being following in a vehicle from Colusa to the Bayliss area. She told investigators she drove on rural roads to try to get away and ended up at a dead end. A man allegedly got out of his vehicle, hit the victim, sexually assaulted her, then drove off. The Sheriff's Office learned of the alleged assault last week. The suspect is described as a Portuguese or Hispanic man driving a silver truck.
