ORROCK TOWNSHIP --A 13-year-old Coon Rapids boy is dead after he crashed his snowmobile in Sherburne County Sunday.

Sheriff's deputies were called to the crash scene at a parking lot in the Sand Dunes State Forest just before 2:30 p.m. Officers found Mitchell Johnson unconscious with head injuries and performed C-P-R until paramedics arrived and pronounced him dead at the scene.

Authorities say the teen was crossing the parking lot and as he went over a snow bank the sled left the ground. That's when Johnson apparently lost control, accelerated and crashed into a group of trees.

The boy was wearing a helmet at the time of the crash.
