SUPERIOR, Wis. (WRN) — A Minnesota man dies in a northern Wisconsin ATV crash.

The Douglas County Sheriff’s Office and Wisconsin Department of Natural Resources are investigating last Saturday afternoon’s head-on collision that killed 72-year-old Ross Frederickson of Eagan.

According to a sheriff’s news release, a 38-year-old Wisconsin man operating a UTV was passing other riders when he collided with Fredrickson’s ATV on a road about 40 miles southeast of Superior. Fredrickson was thrown from his machine, and lifesaving efforts were not successful.

A 42-year-old woman on the UTV was taken to a hospital with a head injury. Fredrickson’s death is the 15th off-road vehicle fatality in Wisconsin this year.
