WHITE PIGEON, Mich. (AP) — Officials say a 77-year-old driver of a semi-truck from Illinois has died in a collision with a slow-moving freight train in southwestern Michigan.

The Kalamazoo Gazette reports (http://bit.ly/OHchI0 ) the driver is identified as Bobby Abell, of Quincy.

The St. Joseph County sheriff's department says the crash around 5 p.m. Thursday near White Pigeon caused at least one car on the train to derail and tip, blocking traffic in the area.

An autopsy is planned to determine whether Abell had a medical problem that may have led to the crash, which is under investigation. Witnesses told investigators that the semi-truck driven by Abell didn't appear to slow down prior to the collision with the train.

An engineer on the train had what were described as minor injuries.
