Fox Lake police responded to a report of a crash about 4:30 p.m. Tuesday on State Park Road at Kohl Avenue, according to a news release from the Fox Lake Police Department.
An autopsy performed Wednesday found Samual J. Wiesbrock died from blunt trauma to the head despite wearing a helmet, McHenry County Coroner Anne Majewski said in a news release. Toxicology testing is pending.
Wiesbrock was riding a Yamaha motorcycle north in the southbound lane of State Park Road near Kohl Avenue to pass vehicles in the northbound lane when a Chevrolet passenger car turned left onto Kohl Avenue from the northbound lane, police said.
Wiesbrock hit the driver’s side of the vehicle and on impact was ejected from his motorcycle, police said.
Wiesbrock was taken to Centegra Hospital – McHenry, where he was pronounced dead at 5:20 p.m., Majewski said. No one else was injured in the crash.
The crash shut down State Park and Grass Lake roads during the evening rush hour Tuesday and backed up traffic in the area. The road reopened about 8:50 p.m.
The crash still is under investigation by Fox Lake police and the coroner’s office, police said.
