Officials suspect alcohol was the cause of a one-vehicle accident Sunday morning on Red Canyon Road, which sent six passengers and the driver to area hospitals. According to Sgt. Shawn Olmstead of the Colorado State Patrol in Glenwood Springs, the vehicle was traveling south around 3 a.m. when it spun clockwise as it skidded off the left side of the dirt road. It collided with a metal post and the embankment, rolling onto its top before coming to a stop facing south. Five of the seven victims suffered minor injuries, though the driver and one passenger suffered moderate to serious injuries. The occupants and the driver were taken to Valley View Hospital in Glenwood Springs. The occupant with the most severe injuries was flown to St. Mary’s Hospital to be treated for a serious head injury. The front-seat passenger was the only person wearing a seat belt and suffered only minor injuries. The cause of the accident is still under investigation, Olmstead said.
