The bodies of 46 people believed to be migrants were found dead in a tractor-trailer in San Antonio on Monday in what officials called the region’s worst mass-casualty event in recent history.
Around 5:50 p.m., a nearby worker heard a cry for help and found a trailer with the doors partially open, San Antonio Police Chief William McManus said. The worker opened the doors, found “a number of deceased individuals inside” and called police.
Firefighters found a body outside the trailer and several inside in the area of 9600 Quintana Road, San Antonio Fire Chief Charles Hood said.
First responders described seeing bodies piled on top of one another inside the trailer.
Sixteen survivors — 12 adults and four minors — were taken to hospitals, Hood said.
“The patients that we saw were hot to the touch,” he said. “They were suffering from heat stroke, heat exhaustion. (There were) no signs of water in the vehicle. It was a refrigerated tractor-trailer, but there was no visible, working AC unit on that rig.”
Temperatures in the area were as high as 99 degrees Monday.
Those who survived, mostly young adults, were too weak to get out of the trailer, Hood said.
Three people are in custody, McManus said, but authorities “don’t know if they are absolutely connected to this or not.” The investigation has been turned over to U.S. Homeland Security Investigations, McManus said.
Federal agents responded to a call reporting “an alleged human smuggling event” from San Antonio police, a spokesperson for Homeland Security Investigations told The Times.
Agents arrived at the scene on Quintana Road near Cassin Drive, the spokesperson said.
“HSI San Antonio has initiated an investigation with support of SAPD,” the spokesperson said. “Details will be released as they are available, the criminal investigation remains ongoing.”
San Antonio Mayor Ron Nirenberg called the deaths “nothing short of a horrific tragedy.”
“We know of 46 individuals who are no longer with us who had families, who were likely trying to find a better life, and we have 16 folks who are fighting for their lives in the hospital,” Nirenberg said. “Our focus right now is to try to bring aid to them as as best we can.”
Local TV news footage showed San Antonio police blocking a narrow road near railroad tracks. Several ambulances were on scene as authorities surrounded the tractor-trailer.
Smuggling migrants in tractor-trailers is a common practice along the Southwest border.
In 2003, 19 people died after they were abandoned in a trailer at a truck stop in Victoria, Texas. The driver in that case, Tyrone Mapletoft Williams, was convicted and is serving a sentence of nearly 34 years in prison.
In 2017, 10 people died after they were left in a tractor-trailer outside a Walmart in San Antonio. The driver, James Matthew Bradley Jr., was sentenced to life in prison without parole.
Last year, 55 migrants who were being smuggled through Mexico died in a tractor-trailer crash near the Guatemalan border.
Monday’s discovery appears to mark one of the deadliest migrant-smuggling incidents in recent U.S. history.
