AP sources: At least 40 people found dead in back of tractor trailer

SAN ANTONIO (AP) — A U.S. official says at least 40 people have been found dead inside a tractor-trailer in a presumed migrant smuggling attempt in South Texas.

The official says 15 others in the truck were taken to hospitals in the San Antonio, where the bodies were found Monday. The official spoke to The Associated Press on condition of anonymity because the information had not been authorized for public release.

It may be the deadliest tragedy among thousands who have died attempting to cross the U.S. border from Mexico in recent decades. Ten migrants died in 2017 after being trapped inside a truck that was parked at a Walmart in San Antonio. In 2003, 19 migrants were found in a sweltering truck southeast of San Antonio.

Big rigs emerged as a popular smuggling method in the early 1990s amid a surge in U.S. border enforcement in San Diego and El Paso, Texas, which were then the busiest corridors for illegal crossings.

Before that, people paid small fees to mom-and-pop operators to get them across a largely unguarded border. As crossing became exponentially more difficult after the 2001 terror attacks in the U.S., migrants were led through more dangerous terrain and paid thousands of dollars more.

Heat poses a serious danger, particularly when temperatures can rise severely inside vehicles. Weather in the San Antonio area was mostly cloudy Monday, but temperatures approached 100 degrees.

Some advocates drew a link to the Biden administration’s border policies. Aaron Reichlin-Melnick, policy director at the American Immigration Council, wrote that he had been dreading such a tragedy for months.

“With the border shut as tightly as it is today for migrants from Mexico, Guatemala, Honduras and El Salvador, people have been pushed into more and more dangerous routes. Truck smuggling is a way up,” he wrote on Twitter.

Stephen Miller, a chief architect of former President Donald Trump’s immigration policies, said, “Human smugglers and traffickers are wicked and evil” and that the administration’s approach to border security rewards their actions.

Texas Gov. Greg Abbott, a Republican running for reelection, was blunt in a tweet about the Democratic president: “These deaths are on Biden. They are a result of his deadly open border policies.”

Migrants — largely from Mexico, Guatemala, Honduras and El Salvador — have been expelled more than 2 million times under a pandemic-era rule in effect since March 2020 that denies them a chance to seek asylum but encourages repeat attempts because there are no legal consequences for getting caught. People from other countries, notably Cuba, Nicaragua and Colombia, are subject to Title 42 authority less frequently due to higher costs of sending them home, strained diplomatic relations and other considerations.

U.S. Customs and Border Protection reported 557 deaths on the southwest border in the 12-month period ending Sept. 30, more than double the 247 deaths reported in the previous year and the highest since it began keeping track in 1998. Most are related to heat exposure.

CBP has not published a death tally for this year but said that the Border Patrol performed 14,278 “search-and-rescue missions” in a seven-month period through May, exceeding the 12,833 missions performed during the previous 12-month period and up from 5,071 the year before.
