A man that was struck by a vehicle after exiting his car and walking into traffic near Wauconda over the weekend has died, police said.

The Wauconda Fire District and Lake County Sheriff’s Office responded around 11:45 p.m. Saturday to Route 120 west of Fisher Road in Wauconda Township, which is near Lakemoor and Volo, for a report of a vehicle crash.

Sheriff’s deputies arrived and located a pedestrian, identified as a 34-year-old Grayslake man, with life-threatening injuries, according to Lake County Sheriff Spokesman Lt. Christopher Covelli.

A preliminary investigation shows the pedestrian exited a vehicle on Route 120 minutes before the crash and began walking.

The pedestrian was walking along the shoulder when he entered the westbound lanes of Route 120.

A westbound Chevrolet Impala, driven by a 30-year-old Round Lake man, struck the pedestrian.

Covelli said the victim was initially transported by ambulance to Advocate Good Shepherd Hospital in unincorporated Barrington.

Due to the severity of his injuries, he was then transferred by medical helicopter to Advocate Lutheran General Hospital in Park Ridge.

The victim was later pronounced dead at Advocate Lutheran General Hospital, Covelli said on Monday.

Sheriff’s crash investigators are working to determine if impairment was a factor in the crash and why the pedestrian exited a vehicle on a busy roadway, Covelli said.

The crash remains under investigation by the Lake County Sheriff’s Office Technical Crash Investigations Unit.
