Christian Martinez, 28, who was arrested on Tuesday in Palestine, Texas, was charged with one count of conspiracy to transport undocumented migrants resulting in death, the DOJ said.
If convicted, both Zamorano and Martinez could face up to life in prison or could face the death penalty. CNN has been unable to determine if Zamorano or Martinez has an attorney.
When police arrived on scene Monday, they discovered multiple people inside the tractor-trailer, some on the ground and in nearby brush, “many of them deceased and some of them incapacitated,” according to the DOJ release.
“SAPD officers were led to the location of an individual, later identified as Zamorano, who was observed hiding in the brush after attempting to abscond. Zamorano was detained by SAPD officers,” the release said.
Laredo Sector Border Patrol also provided Homeland Security Investigations agents with surveillance footage that showed the tractor-trailer crossing through an immigration checkpoint, according to the release. The driver could be seen wearing a black shirt with stripes and a hat.
“HSI agents confirmed Zamorano matched the individual from the surveillance footage and was wearing the same clothing,” the release read.
An investigation revealed that communications occurred between Zamorano and Martinez concerning the smuggling event, according to the release.
The attorney for D’Luna-Mendez said he does not comment on pending cases. CNN has reached out to the D’Luna-Bilbao’s attorney and has not heard back.
No water or working AC inside trailer, fire chief said
The refrigerated semitractor-trailer had no visible working air conditioning unit and there was no sign of water inside, San Antonio Fire Chief Charles Hood told reporters Monday. It’s not clear how long people inside the truck had been dead, he said.
High temperatures Monday in the San Antonio area ranged from the high 90s to low 100s, according to the National Weather Service.
“None of these people were able to extricate themselves out of the truck,” Hood said. “So they were still in there, awaiting help, when we arrived … meaning just being too weak — weakened state — to actually get out and help themselves.”
Craig Larrabee, Homeland Security Investigations San Antonio acting special agent in charge, described it as “the worst human-smuggling event in the United States.”
“In the past, smuggling organizations were mom and pop. Now they are organized and tied in with the cartels. So you have a criminal organization who has no regard for the safety of the migrants. They are treated like commodities rather than people,” Larrabee told CNN in a phone interview.
Business owners in the area where the trailer was found told CNN they were in shock.
“They were human beings, it was terrible,” said Israel Martinez, 68, co-owner of USA Auto Parts. “We (migrants) come to this country for a better life and yesterday reminded many of us that sadly, some of us achieve it but many others don’t do it.”
