The disappearance and death of Alejandro Jacomino Gonzalez has triggered an FBI investigation, with agents piecing together a timeline that spans two states.

Gonzalez, a commercial truck driver, picked up a shipment of vehicles on April 16 at the Port of Brunswick, Georgia, and was heading to Miami. He pulled into a rest stop on I-95 in Brevard County, Florida, at about 1:20 a.m. on April 17, roughly halfway through his trip, according to the FBI.

Hours later, the GPS unit on his tractor-trailer showed the truck moving again, departing the rest stop around 7:50 a.m. The route was perplexing: after briefly continuing south on I-95 to the first exit, the truck turned around and headed north back toward Georgia, the FBI said.

That afternoon, the tractor-trailer was found abandoned in Port Wentworth, Georgia, just west of Savannah — roughly 320 miles from the rest stop. Inside, Gonzalez and several of the cars he had been hauling were missing, the FBI said. Three of those vehicles were later recovered in Florida; others have not been located.

On the same day, a body was discovered in Glynn County, Georgia, a coastal area about 80 miles south of where the semitrailer was found. Authorities later confirmed it was Gonzalez’s remains. FBI spokesman Tony Thomas, based in Atlanta, declined Thursday to release additional details, saying the investigation remains active.

No charges have been filed and no arrests announced.

The FBI had issued a missing-person bulletin for Gonzalez late last week, describing him as 41 years old. The case has drawn attention to the vulnerability of long-haul truck drivers who often travel alone with valuable cargo.
