An 18-year-old man was killed after he was partially ejected from his car when he lost control of the vehicle and rolled it over near Wauconda Wednesday evening.

The Lake County Sheriff’s Office and Wauconda Fire District responded around 10:20 p.m. Wednesday to the 29300 block of North Callahan Road in unincorporated Wauconda for a serious vehicle crash.

Lake County Sheriff’s Office Deputy Chief Christopher Covelli said sheriff’s deputies arrived and located a 2000 Jeep Wrangler rolled over with major damage.

A preliminary investigation shows the driver of the Jeep, an 18-year-old Wauconda man, was traveling northbound on Callahan Road just north of Old Rand Road.

For an unknown reason, the driver of the Jeep failed to negotiate a curve in the roadway and drove onto the gravel shoulder, Covelli said.

The driver overcorrected, which caused the Jeep to slide into a ditch on the west side of the roadway.

The Jeep then struck several large rocks, causing it to roll over.

The driver, who does not appear to have been wearing a seatbelt, was partially ejected and sustained major injuries, Covelli said.

He was pronounced dead at the scene.

The Lake County Coroner’s Office responded to the scene and an autopsy is being conducted Thursday morning.

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