Six People Found Dead Inside a Union Pacific Boxcar at a Texas Border Rail Yard

Six people were found dead inside a Union Pacific cargo train boxcar at a rail yard in Laredo, Texas on Sunday afternoon. The discovery was made just after 3:30 p.m. local time near mile marker 13 on Jim Young Way, on the outskirts of the city — approximately 160 miles south of San Antonio, along the southern border.

A Union Pacific employee called police after discovering multiple casualties inside the boxcar during an inspection. When first responders arrived, they confirmed all six individuals were dead. No one else was found alive inside the railcar.

What Is Known

As of Sunday evening, investigators had not released the identities, ages, or genders of the six victims. The origin of the train had not been publicly disclosed. The cause of death has not been determined and will be established by the Webb County Medical Examiner's office.

Laredo Police Department investigator Jose Baeza told reporters those questions are "at the crux of the ongoing fluid investigation," describing the scene as still in a very early phase. The Laredo Police Department confirmed it is working with Union Pacific and other law enforcement agencies to investigate the circumstances surrounding the deaths.

Temperatures in Laredo on Sunday afternoon were in the low-to-mid 90s. Whether heat played a role in the deaths has not been confirmed, though investigators have not ruled it out.

Union Pacific said in a statement that the company was "saddened" by the incident and is "working closely with law enforcement to investigate." The railroad did not release additional details. Union Pacific operates across the US-Mexico border and is the only railroad that services all access points into Mexico.

The Broader Context

The discovery in Laredo is the latest in a long and grim pattern of deaths connected to freight train cars along the Texas border. The region has seen repeated tragedies involving people found dead or in distress inside train cars and tractor trailers over the years.

In 2023, migrants were found dead in Union Pacific boxcars in both Uvalde County and Eagle Pass on consecutive days. In 2022, 53 migrants were found dead inside a sweltering tractor trailer in San Antonio in one of the deadliest human smuggling incidents in United States history.

The Laredo rail yard sits in Webb County, one of the most active smuggling corridors on the southern border. The city of Laredo is a major crossing point for both legal commerce and illegal crossings between the United States and Mexico. Union Pacific's rail network connects directly to the Mexican rail system at several points along the border, making freight cars a known route for smuggling operations.

Investigation Ongoing

No federal agencies have publicly confirmed involvement in the investigation as of Sunday evening, though cases of this nature typically involve Homeland Security Investigations, U.S. Border Patrol, and potentially the FBI depending on the circumstances and the nationalities of the victims.

The identities of the six victims have not been released, and it remains unclear how long they had been inside the boxcar before they were found. Investigators have offered no timeline and have not publicly characterized the deaths as migrant-related, though the location and circumstances are consistent with prior incidents along the same corridor.

The Webb County Medical Examiner's determination of cause of death will be a key factor in shaping the direction of the investigation. Until those findings are released, the circumstances surrounding the deaths of the six people found in that boxcar on Sunday afternoon remain officially unknown.
