A Red Bluff man has been sentenced to prison for sexually assaulting a guest during a party at his home. The victim became extremely intoxicated while at the home of 51-year-old Jamie Jessie Grant Markes. Her friends cared for her and laid her down in a bed to sleep it off for a while. At some point Markes went into the room where the woman was laying down, still unable to care for herself, and he sexually assaulted her with a foreign object. He’s been sentenced to 6 years in state prison.
