A 36-year-old Happy Valley man has been sent to prison for vehicular manslaughter and hit and run. In July of 2013 Justin Arrowsmith was sitting on a camouflage Quadrunner in the dark on Lassen Avenue in Happy Valley talking to two people when Bryan Reed came along on a Harley-Davidson and rear-ended the quad. The collision threw 41-year-old Gina Hansen to the ground, causing head and neck injuries and she was pronounced dead on arrival at the hospital. Arrowsmith was drunk and reed was allegedly on Methamphetamine. Reed’s case is still pending. Arrowsmith fled to his home, where he was found an hour and a half later. He eventually admitted he had fled because he was scared. Arrowsmith, who has four prior DUI’s, was found guilty by a jury last month and he was sentenced Monday to 8 years in state prison.
