A Texas man has pleaded guilty for his involvement in a human smuggling and trafficking operation that led to the tragic deaths of 53 migrants at San Antonio tractor-trailer tragedy in the previous year, PEOPLE reports.

Christian Martinez, aged 29, hailing from Palestine, Texas, has acknowledged his role in this heinous crime.

The United States District Attorney's Office for the Western District of Texas made this announcement in a press release issued on Wednesday.

San Antonio Tractor-Trailer Tragedy

The tragic incident that unfolded in June 2022, at that time referred to as the deadliest human smuggling event in U.S. history, sent shockwaves across Mexico, Guatemala, and Honduras, leaving grieving families in its wake as authorities identified the deceased within the abandoned truck.

Numerous individuals, including Christian Martinez, were indicted by federal grand juries in connection with this smuggling operation, according to CNN.

The alleged driver of the tractor-trailer, Homero Zamorano Jr., aged 47, from Elkhart, Texas, also faces charges related to this case, according to the U.S. Attorney's Office.

The indictment suggests that Martinez transported Zamorano from Palestine to San Antonio, where Zamorano loaded the migrants onto the tractor-trailer.

The Department of Justice reports that at least 66 migrants, including eight children and a pregnant woman, were loaded onto the truck.

Furthermore, Martinez and others played a role in coordinating, facilitating, and communicating about the tractor-trailer's progress.

Authorities were able to link Zamorano and Martinez to the operation through surveillance footage and phone communications obtained via a search warrant.

Tragically, in addition to the 53 lives lost, nearly a dozen others on the truck required hospitalization due to heat-related conditions. The refrigerated semitractor-trailer lacked a visible working air conditioning unit water, and the passengers were unable to exit the vehicle, as confirmed by San Antonio Fire Chief Charles Hood.

4 Members of Migrant Smuggling Ring Also Plead Guilty in Corpus Christi

In a separate but related development, several members of an undocumented migrant smuggling ring have pleaded guilty to their involvement in a deadly human smuggling operation, said 3 News.

This network conspired to transport undocumented migrants, resulting in the death of eight and injuries to two others.

The probe by Homeland Security Investigations revealed that the group attempted to smuggle people by water from South Padre Island to Corpus Christi, Texas, in February 2022, leading to the capsizing of the watercraft and the tragic deaths of four migrants.

In a prior incident in 2019, the suspects were involved in a crash while attempting to smuggle migrants from the Rio Grande Valley to Houston, resulting in four fatalities.

All four individuals involved in this case face potential life imprisonment and fines of up to $250,000, with sentencing set for December 20, as determined by U.S. District Judge Roland Olvera.
