Authorities have identified two people killed when their snowmobiles collided on a trail in Michigan's Upper Peninsula.
The Alger County sheriff's office says 21-year-old Douglas Show of Mill Run, Pennsylvania, and 54-year-old John Shadian of Kenosha, Wisconsin, died Monday night in Rock River Township.
Show and Shadian were thrown from the snowmobiles and pronounced dead at the scene after crashing head-on. An investigation reveals that excessive speed is believed to be the cause of the accident.
Rock River Township is southeast of Marquette.
