A Brookfield man was killed and a state trooper injured early Saturday morning when a car slammed into the rear end of a state police squad car on eastbound I-290 in Addison near Mill Road.

According to Illinois State Police, Frank S. Caruso was waiting in the rear seat of the trooper’s squad car keeping warm while waiting for a tow truck when a grey Chevy Impala reportedly driven by Chicago resident Daniel Clark, plowed into the squad.

The impact killed Caruso, 42, and injured the trooper, who was reportedly also inside the front seat of the squad car.

Clark, 32, was charged with aggravated driving under the influence causing death and aggravated DUI causing great bodily harm. At a bond hearing Sunday, a DuPage County judge set Clark’s bond at $1 million. He remains at DuPage County Jail awaiting trial.

The state trooper had responded to the scene at about 1 a.m. to investigate a one-car crash that was partially blocking the left lane of traffic on I-290. Caruso reportedly lost control of his gray 2005 Nissan SUV and it struck the inside wall, disabling the vehicle.

The state trooper parked his squad car behind the disabled vehicle and left the squad’s emergency lights on to warn approaching motorists.

While the trooper conducted his investigation and awaited a tow truck, Caruso sat in the rear of the squad car to keep warm. At about 1:20 a.m., Clark reportedly drove into the squad car.

Caruso, formerly of Oakbrook Terrace, was taken to Elmhurst Hospital where he was pronounced dead at 2:15 a.m. The trooper suffered a concussion, according to state police. He was taken to Loyola University Medical Center in Maywood.
