Police in western Michigan say a man fell asleep at the wheel of his parked vehicle and accidentally ran over a tent containing his wife and two young children.

Norton Shores police Lt. Jon Gale tells The Muskegon Chronicle the accident happened around 6 a.m. Wednesday at P.J. Hoffmaster State Park.

The man was trying to warm up the family vehicle but fell asleep behind the wheel. The vehicle then rolled forward over the family's camping tent.

The Grand Rapids Press reports a 6-year-old child was flown to a Grand Rapids hospital for treatment. The woman and a 2-year-old child were taken to a Muskegon hospital but weren't seriously injured.
