A Naperville man was critically injured early Wednesday when he was hit by a semitrailer on Interstate Highway 294 in Des Plaines as he fled the scene of a stabbing, authorities said this afternoon.

The employee apparently was waiting for his boss to show up before the boss went to a gym for his usual morning workout, Prandini said. The employee told his boss that his vehicle had broken down, and the boss allowed the employee to get into his car. The employee pulled a steak knife from his duffel bag and stabbed his employer, Prandini said.
The man then ran away and got onto the northbound lanes of the Tri-State Tollway at Touhy Avenue, where the semi hit him, throwing him 30 feet, said Master Sgt. Carlita Joe of the Illinois State Police.
