The Rock County Medical Examiner releases the name of the Janesville teenager who died Saturday night in a single-vehicle crash in Janesville.

Janesville Police were called to the area of Palmer Drive and South Main Street about 10:45 p.m. for a single vehicle crash.

Officers say they found 18-year-old Grant R. Mullen of Janesville pinned in the vehicle and dead at the scene.

The initial investigation determined Mullen was westbound on Palmer Drive passing Rotary Gardens when he failed to negotiate a curve.

The vehicle left he road and hit a tree.

The Medical Examiner says preliminary results of the autopsy confirm Mullen died from injuries sustained in the crash.
