Sheriff’s officials in Pottawattamie County says a tractor trailer driver who had been missing, was found dead inside the cab of his semi Monday at a rest stop which is under construction, near Shelby. Corporal Nick Amdor, with the Pott County Sheriff’s Office, says the 58-year-old trucker from Monmouth, Ill., appeared to have died of natural causes, but Amdor declined to release the man’s name until his relatives had been notified.

Amdor says it appears the man died Friday evening or Saturday morning.  His body was found in the cab’s sleeper compartment. The semi was still covered in snow when a co-worker found the truck and the body about 7:15 p.m. Monday. The trucking company he had worked for, out of Burlington, had asked its drivers to be on the lookout for the semi-trailer truck, and had notified law enforcement offices along the driver’s route.

Corporal Amdor says while the rest stop near Shelby is under construction,  truckers are still able to pull in for the night to get some sleep.
