Authorities say a 19-year-old man is dead and another is injured following an off-road vehicle accident at Silver Lake State Park in West Michigan.
Published reports say the man from Oakland County's Oakland Township died after two people in a group of four riding quads on the park's dunes collided Thursday evening in Oceana County. The two uninjured riders called 911 afterward.
Investigators say the third rider in line nose-dived into an embankment and the fourth rider landed on top of the crashed rider, who died.
The crash is under investigation. Sheriff's Lt. Craig Mast says it was the first time the four riders had been to Silver Lake State Park, located along Lake Michigan.
