The coroner has identified a 73-year-old man and said he died of natural causes before crashing into a semi-truck on Route 120 in Grayslake Friday morning.

An autopsy showed that James Bechtel, 73, of Grayslake, died of natural causes prior to being involved in a crash, according to Lake County Chief Deputy Coroner Steve Newton.

The Grayslake Fire Protection District and Grayslake-Hainesville Police Department responded around 5:25 a.m. Friday to the area of the Starbucks, 775 East Belvidere Road in Grayslake, for a vehicle crash with injuries.

Grayslake Deputy Police Chief Jeff Myhra said a blue Chevrolet Trailblazer and an International semi-truck were involved in a crash.

An investigation showed the Chevrolet was traveling eastbound on Route 120.

Bechtel experienced a medical emergency that caused him to drive into oncoming traffic, Myhra said.

The semi-truck, which was traveling westbound on Route 120, collided with the Chevrolet.
