The coroner’s office has identified a Highwood man who is believed to have had a medical event that caused him to drive off Interstate 94 and into a lagoon.

An autopsy conducted on Jason Raynor, 42, of Highwood, showed he likely suffered a medical event that resulted in a crash, according to Lake County Coroner Jennifer Banek.

Raynor had no significant injuries from the crash, Banek said.

The Illinois State Police and Northbrook Fire Department responded around 3:30 p.m. Tuesday to Interstate 94 northbound at Dundee Road for a report of a single-vehicle crash.

Troopers arrived to find a black 2016 Land Rover Discovery that had driven off the interstate, crashed through a fence and came to a rest in water.

A preliminary investigation showed the Land Rover, driven by Raynor, was traveling northbound on Interstate 94 south of Dundee Road.

Raynor apparently suffered from a medical event, lost control of his vehicle and drove off the right side of the roadway.

The Land Rover was submerged in approximately three feet of water off the right side of the roadway, state police said.

Raynor was transported to Highland Park Hospital where he was pronounced dead.

The incident remains under investigation by Illinois State Police and Lake County Coroner’s Office.
