By Jim Reece - Driving Under the Influence charges were filed after two crashes this weekend on Amador County Roads, including one with major injuries. The Amador Unit of the CHP reported arrests in both cases. CHP said at 5:30 p.m. Saturday, Mathew Marton, 26, of Turlock was driving a 1993 GMC pickup truck while intoxicated at a high rate of speed on Campo Seco Road, west of Watertown Road. Due to his intoxication, Marton failed to negotiate a curve in the road, and the front wheels of his truck left the road and the vehicle hit a tree. His passenger, Tresa Giannini, of Sutter Creek, suffered major injuries. Both extricated themselves and flagged down a passing motorist. They were taken to Sutter Amador Hospital and Marton was arrested for felony DUI. At CHP reported another DUI arrest 9:15 p.m. Sunday. Preston E. Vanslochteren, 52, of Ione, was riding his 2004 Harley Davidson motorcycle west bound on Reservation Road, east of Camanche Road. Due to his intoxication, he allowed the motorcycle to drift off the paved portion of the road and into the drainage gully, where the motorcycle flipped, throwing off the rider. CHP responded and arrested Vanslochteren for DUI and booked him into the Amador County Jail.
