The FBI is investigating the death of a truck driver whose body and semitrailer were found in different areas of southeastern Georgia hours after he was last seen alive at a Florida rest stop. Alejandro Jacomino Gonzalez, 41, went missing while heading to Miami with a shipment of vehicles he picked up April 16 at the Port of Brunswick on the Georgia coast, according to the FBI.

His tractor-trailer was found later that day about 320 miles (515 kilometers) away in Port Wentworth, Georgia, west of Savannah.
