Seven Deaths Tied to Human Smuggling in Texas Railcars

On Sunday, May 12, 2026, a Union Pacific worker found six dead migrants in a sealed shipping container at the Laredo rail yard, Texas, the nation’s largest inland port on the U.S.–Mexico border. A seventh body was recovered near railroad tracks in San Antonio on Monday, May 13, and investigators link it to the same smuggling operation. Autopsies identified three victims from Mexico and three from Honduras, including a 14-year-old boy; all died of hyperthermia. Temperatures in Laredo peaked at 97 °F (36 °C) as the train traveled south.

Webb County Medical Examiner Dr. Corrine Stern ruled the 29-year-old Mexican woman’s death an accidental heatstroke and estimates all six victims died within eight hours of exposure. The seventh victim’s cause of death remains pending. Fingerprint matches are being run through the U.S. Border Patrol’s Missing Alien Program.

Texas has seen multiple train-related smuggling deaths. In 2022, 53 migrants perished in a tractor-trailer near San Antonio; two smugglers received life sentences for that case in June 2025. Union Pacific uses inspection portals and imaging to spot unauthorized occupants, yet sealed containers remain exploitable.
