Police believe the polar vortex was a factor in the death of a 69-year-old FedEx worker whose body was discovered outside of a delivery hub on Thursday morning in Illinois. Police Capt. Darren Gault told CNN that a co-worker found the man’s body between two tractor-trailers at a delivery hub in East Moline. According to the network, the hub was closed on Wednesday and it was not clear why or how long the worker had been there. “We are saddened by the loss of our team member and our sympathies go out to his family and friends,” FedEx said in a statement Friday. “We are working with local authorities as they investigate.” The network reports that temperatures in the East Moline area dipped to the negative thirties on Wednesday night and Thursday morning as a result of the polar vortex that has taken at least 20 lives thus far. Weather-related deaths were reported in states like Illinois, Michigan, Minnesota, Indiana, Wisconsin, and New York.
