The 18-Wheeler Human Smuggling Case James Matthew Bradley Jr. was driving an 18-wheeler full of undocumented migrants. when he pulled into a Walmart parking lot on the city’s South Side. While some fled the scene as soon as they arrived, police at the scene discovered 38 people packed into the truck’s windowless, sweltering trailer. In total, 10 men died from the incident and dozens more were left with serious heat-related injuries. Bradley claimed to have not known what was inside the trailer, and said he only discovered the migrants when he pulled over to use the bathroom and heard banging noises.

A federal grand jury indicted James Bradley, Jr. on five criminal charges Wednesday for his role transporting dozens of undocumented immigrants in an unventilated, crowded semi truck in July. The incident left ten passengers dead.

The indictment included charges of “conspiracy to transport aliens” for financial gain resulting in death and possession of a firearm by a convicted felon. If convicted, Bradley could face life in prison — or the death penalty.

For now, 22 of the surviving passengers of Bradley’s trip are being held in federal detention as potential witnesses in Bradley’s case. The feds fear they’ll leave the country if they don’t keep them behind bars.

Bradley initially told authorities he had no idea that there were immigrants packed into the back of his truck, and that he only heard their desperate banging from inside the trailer when he pulled over to use the restroom at a San Antonio Walmart.

Passengers, however, told the police they were greeted by SUVs at the Walmart parking lot, which quickly whisked away as many immigrants they cram inside. It appeared planned. Walmart surveillance videos back up this testimony.

Bradley will remain in federal custody until his trial date, which has yet to be set.
