Truck driver Stanley Kasprzyk, 58, had been missing since last Tuesday after picking up a load of steel from Kenwall Steel in Dearborn, Michigan.
Chicago police put out a community alert, attempting to locate the missing driver. This week, his family received bad news as he was found dead in his truck, with the engine still running. It is believed he suffered a heart attack shortly after picking up the load.
Police were able to locate the driver by tracking the satellite position of his cell phone.
