A 73-year-old man who suffered critical injuries after his Tesla and an SUV collided in Barrington Hills has died in the hospital, authorities said.

The Barrington Hills Police Department and Barrington-Countryside Fire Protection District responded around 2:13 p.m. November 4 to Route 68 and Route 59 for a report of a vehicle crash with injuries.

Barrington Hills Police Department Public Information Officer William Walsh said the incident involved a 2020 Tesla and a 2013 Nissan Rogue.

A preliminary investigation shows the Nissan and the Tesla collided in the intersection. It is unknown which vehicle was at fault.

Walsh said the driver of the Tesla, a 73-year-old man from Barrington Hills, suffered life-threatening injuries.

The man was identified as Charles Dietz Jr., according to the Cook County Medical Examiner’s Office.

Fire department radio traffic at the time indicated Dietz was unconscious and not breathing at the crash scene.

Paramedics transported Dietz to Advocate Good Shepherd Hospital in Barrington.

The driver of the Nissan, a 34-year-old man from Lake in the Hills, was not seriously hurt.

The Major Crash Assistance Team of Lake County was activated and responded to the scene.

Traffic was diverted from the intersection for approximately four hours with the assistance of the Hanover Township Emergency Services, Walsh said.

The medical examiner’s office said Dietz was pronounced dead at Lutheran General Hospital in Park Ridge last Saturday, more than a week after the crash.

Dietz’s obituary said he died while surrounded by his loved ones following the “tragic car accident.”

Dietz leaves behind his wife and three children along with grandchildren and other family members.

A funeral service was held Thursday in Arlington Heights.

The crash remains under investigation by the Barrington Hills Police Department and the Major Crash Assistance Team.
