The rider, a 19-year-old Lake Villa man, was not found until Thursday morning, approximately 16 hours later.

He was located based on a ping from his cell phone that was conducted by his father, Myhra said.

The crash, which had no witnesses, occurred at the curve on Drury Lane south of the golf course.

The motorcycle, a Kawasaki 650 sport bike, and the rider left the roadway far enough that they were not visible to anyone driving along the road, Myhra said.

Myhra said the victim was wearing all of the appropriate safety equipment but still suffered critical injuries.

Paramedics transported him to Advocate Condell Medical Center in Libertyville for treatment.

The Kawasaki was traveling eastbound on Drury Lane and failed to navigate the curve for unknown reasons.

Myhra said there is no indication so far that any other vehicles were involved in the crash.

The Lake County Major Crash Assistance Team (MCAT) responded to assist the Grayslake Police Department with the investigation.

Drury Lane was shut down for several hours during the crash investigation.
