Mount Prospect man killed in Deer Park crash

A driver who died after a weekend car crash in Deer Park has been identified as a Mount Prospect resident, authorities said Tuesday.

Robert Clauss, 71, was fatally injured in Sunday’s collision, the Lake County coroner’s office said following an autopsy. A passenger in his car and the driver of a second car were hurt but survived, authorities said.

The crash occurred about 10:20 a.m. Sunday at Lake-Cook and Ferndale roads, according to the Lake County Sheriff’s Office.

A 2025 Jeep Wrangler was turning from eastbound Lake-Cook Road onto northbound Ferndale Road and drove into the path of a westbound 1986 Alfa Romeo being driven by Clauss, a sheriff’s spokesperson said.

Clauss died at Advocate Good Shepherd Hospital near Barrington. A 63-year-old passenger also was hurt and was in serious condition at the hospital Monday, officials said.

The 75-year-old Deer Park man driving the Jeep suffered minor injuries. He reportedly didn’t see the other car when he began turning, the spokesperson said.

The sheriff’s office is investigating.
