BEAVER CREEK — Jade Thomas, 21, of Sioux Falls, South Dakota faces a maximum of three years in prison for a criminal charge relating to a Monday morning crash in Rock County.

State patrol was dispatched to the scene of a traffic accident on Interstate 90 near Beaver Creek, where a vehicle had collided with the guard rail. The passenger had already been transported by ambulance to a nearby emergency room for treatment of injuries.

When an officer arrived at the scene, the driver, Thomas, was outside the vehicle. The officer observed a beer can on the ground near the vehicle and reported smelling alcohol inside the vehicle.

Thomas allegedly told law enforcement she had fallen asleep at the wheel, then crashed into the guard rail. The officer noticed signs of potential intoxication and had Thomas take field sobriety tests, which revealed a breath alcohol content of 0.174%.

Medical records released by the passenger show that the passenger suffered a fractured rib and required stitches to close a wound caused by broken glass.

Thomas was charged with fourth-degree DWI and with criminal vehicular operation, for which she could serve a maximum sentence of three years in prison and/or pay a $10,000 fine.
