CHICAGO -- Workers at a rail yard on Chicago's West Side made a gruesome discovery: a human foot.
Chicago police say the foot was found inside a boot late Tuesday while the workers were performing maintenance work at the yard.
Authorities say they believe the foot belonged to a man who was struck and killed by an Amtrak train in Racine, Wis., last month. Police say his foot couldn't be found after the accident, and it may have gotten stuck underneath the train only to fall off after the train arrived in Chicago.
The rail yard is shared by Metra and Amtrak trains.
The Cook County medical examiner's office says a pathologist plans to examine the foot.
