EAST MOLINE, Illinois — Police say weather played a part in the death of a FedEx worker whose body was found outside of an Illinois delivery hub Thursday amid sub-zero temperatures.

The worker, a 69-year-old man, was found dead at FedEx Freight in East Moline, according to Rock Island County Coroner Brian Gustafson.

Captain Darren Gault from the East Moline Police Department said another FedEx employee found the worker’s body between two semi tractors. The discovery was reported around 9:30 a.m.

The East Moline Police Department removed his body from the scene Thursday morning. Gustafson said authorities weren’t sure how long the body had been there before it was found.
