A Big Bear man who crashed head-on into another vehicle in December, killing both occupants of the other car, was arrested Thursday, charged with vehicular manslaughter and child endangerment. On December 1, Michael Daugherty, now 25, was driving a Dodge Durango northbound on Old Woman Springs Road at about 55 miles per hour when he attempted to pass a tractor-trailer just north of Linn Road. When Daugherty pulled into the southbound lane to pass, he saw a Chevrolet Cavalier, driven by Krue Kornbach, 22, of Johnson Valley, driving toward him in the southbound lane. Both drivers took evasive action, but they collided head on. Karnbach and his passenger, Natalie Craddock, 19, were killed, and Daugherty and his one-year-old daughter were injured in the crash. On Thursday Daugherty was arrested for investigation of vehicular manslaughter and child endangerment. He was booked into West Valley Detention Center with bail set at $300,000.
