LAREDO, Texas (AP) — A Guatemalan man pleaded guilty Wednesday in federal court to a felony offense, acknowledging his role in an attempt to illegally smuggle migrants into the United States, which tragically resulted in a major accident in Mexico that killed over 50 individuals.

Daniel Zavala Ramos, 42, entered his plea in U.S. District Court in Laredo, Texas, admitting to conspiring to transport undocumented migrants from Guatemala through Mexico into the U.S., endangering lives and causing significant injuries and fatalities, according to the U.S. Department of Justice.

Sentence is scheduled for July 7, where Ramos faces the possibility of life in prison.

He was one of six Guatemalans charged in connection to the December 2021 incident, where a tractor-trailer carrying at least 160 migrants overturned after crashing into a pedestrian bridge support structure. Authorities reported that of those aboard, at least 53 died and more than 100 were injured. Disturbing footage showed victims lying in a pile, highlighting the imminent dangers migrants face in these illegal smuggling operations.

Ramos is the first to be convicted among the group, with the others scheduled for their pretrial conference on June 3. As noted by the Justice Department, the deceased included unaccompanied minors.

The crash location was on a highway leading to the Chiapas state capital, approximately 160 miles from Guatemala's border, intensifying the discourse surrounding immigration policies and the risks inherent in undocumented crossings.

According to authorities, the smugglers exploited vulnerable migrants, including unaccompanied children, providing scripts for them to use if caught. They utilized various transportation methods and maintained contact through social media to facilitate the smuggling processes.

This case exemplifies the pressing issues within the migrant smuggling crisis, showcasing the dangerous lengths individuals will go to in search of a better life in the U.S.
