BENTON, Ill. — Troopers have identified an on-duty firefighter killed today when he was hit by a Greyhound bus on Interstate 57 in southern Illinois.

Authorities say 43-year-old James Miller, of Sesser, Illinois, died at the scene.

Illinois state police say Miller and colleagues from the Sesser Fire Protection District had finished putting out a tractor-trailer fire near Benton when the Greyhound hit him.

A spokeswoman for Dallas-based Greyhound says the bus was headed to Chicago from Memphis, Tennessee, and had 51 passengers and the driver.

No one on the bus was hurt.

Trooper David Sneed says the bus driver has been ticketed for failing to give the emergency vehicles an appropriately wide berth along the highway, as well as improper lane usage.
