Authorities said Zamorano, who drove the truck and the other men charged in the smuggling attempt, knew the trailer's air-conditioning unit had malfunctioned and were unable to deliver air to those trapped inside during the sweltering three-hour journey from the border. Immigrants blow air conditioning. Laredo to San Antonio.

Investigators said temperatures reached 100 degrees Fahrenheit (38 degrees Celsius) and the migrants were screaming, banging on the walls of the trailers for help or trying to climb out.

According to Mexican authorities, the truck was carrying 67 people, and the dead included 27 Mexicans, 14 Hondurans, 7 Guatemalans and 2 Salvadorans. Prosecutors say migrants pay up to $15,000 each to be taken across the U.S. border.

The incident occurred on June 27, 2022, on a remote trail in San Antonio. Police took Zamorano into custody after finding him hiding in nearby bushes, a statement from the U.S. Attorney's Office said. A search of Zamorano's phone revealed he had received calls about smuggling activity.

Surveillance video of the 18-wheeler passing through a Border Patrol checkpoint showed the driver matched Zamorano's description, the indictment said.

Previously charged in the tragedy was Christian Martinez, also from Texas, who was arrested along with Zamorano shortly after the migrants were discovered. Martinez has since pleaded guilty to trafficking-related charges.

In 2023, four Mexican citizens were also arrested in the case. In August, a suspect arrested in Guatemala was accused of helping coordinate the smuggling attempt. U.S. authorities said they would seek the extradition of Rigoberto Roman Miranda Orozco, who is charged with six counts of migrant smuggling resulting in death or serious injury. Authorities claimed he was linked to four Guatemalan immigrants in the trailer, three of whom died, and he faces life in prison if convicted.

According to the indictment against Miranda Orozco, smugglers forced migrants to hand over their cellphones before entering the trailers, preventing them from calling for help. An unknown powder was sprinkled around the trailer to prevent patrol dogs at border checkpoints from picking up the scent of human cargo.

By the time the trailers were opened in San Antonio, 48 migrants were dead. Sixteen more people were taken to hospital and five died. President Joe Biden called the tragedy "horrible and heartbreaking."

Those who died were seeking a better life. News of the trailers laden with bodies caused panic in cities and villages accustomed to seeing young people leaving, trying to escape poverty or violence in Central America and Mexico.

Authorities said the men were involved in human smuggling operations in Guatemala, Honduras and Mexico and shared routes, guides, stash houses, trucks and trailers, some of which were stored in a private parking lot in San Antonio.
