The Highland Park Police Department said they are remembering a police officer who was hit by a car and killed in the line of duty during a burglary investigation in Lake Forest 39 years ago today.

The City of Highland Park said they are honoring the memory of Officer Robert C. Reimann Jr., who was killed in the line of duty on January 6, 1984.

Officers lit a flame in his honor beside the memorial stone at the police department Friday morning.

Reimann was struck and killed by a tractor-trailer after stopping a vehicle on Route 41 between Old Elm Road and Westleigh Road in Lake Forest, according to the Officer Down Memorial Page.

He was investigating a burglary that occurred in Highland Park and stopped a car believed to be involved.

As he and other assisting Lake Forest and Highland Park officers questioned the occupants on the side of the roadway, a tractor-trailer entered the area.

The semi-truck collided with the patrol cars and the suspect vehicle, the Officer Down Memorial Page said.

Reimann, who was 32 years old, was struck by the truck and died.

Reimann had served with the Highland Park Police Department for nine years.

He was survived by his wife, father and sister.

“The city gratefully remembers his service to our community each year on the anniversary of his passing,” officials said.

In 2018, the city redesigned the Highland Park Police Department shield patch and included a tribute to Reimann, whose badge number, 21, appears on the sails of the boats that are part of the city seal.

All Highland Park officers honor the memory of Reimann as the shield patch is part of the police department’s uniform, the city said.
