Ogden police believe alcohol was factor in multi-vehicle, hit-and-run crashes that put two people in the hospital, one of them in critical condition. Just before 10 p.m. Thursday, a 2003 Chevrolet Silverado pickup truck, described by witnesses as traveling recklessly and at a high rate of speed, slammed into a 2006 Chevrolet Malibu sedan that was making a left turn at the intersection of 37th Street and Harrison Boulevard.
