A crash killed three males early Friday on Grant Street near I-80/94 in Lake County. Before the crash, Lake County officers had conducted a traffic stop on the vehicle with three occupants near Ridge Road and Grant Street. But while officers were talking to the occupants, the car left the scene at a high rate of speed. Officers attempted to follow the car on Grant Street, but lost sight of it at the I-80/94 overpass. When officers arrived at the overpass, they observed the car had hit a semi tractor trailer. Two of the occupants of the car died at the scene. The third occupant was transported to a local hospital, and succumbed to his injuries. The driver of the semi refused medical treatment at the scene. The Lake County Sheriff’s Department Traffic Unit is investigating the crash.
