More than a dozen undocumented immigrants were taken to hospitals after at least 46 were discovered dead in a tractor-trailer near San Antonio, Texas, according to officials.

According to authorities, two of those evacuated to a hospital eventually passed away, bringing the overall death toll to 48.

Crews were present at the abandoned 18-wheeler with up to 100 migrants inside that was discovered in the 9600 block of Quintana Road.

The find is thought to be a component of a human smuggling scheme.

Authorities at the scene revealed that 46 people had been found dead, but no children. Officials did not specify if the migrants were from Mexico or from anywhere else.

Twelve adults and four children from the tractor-trailer were among the sixteen people who were sent to the hospital.

The tractor-trailer was reported to police by a neighboring worker just before 6 o’clock, according to San Antonio Police Department Chief William McManus. When authorities arrived on the site, they discovered scores of dead people inside the transport vehicle’s rear.

According to him, all of the victims who died displayed signs of heat-related causes of death, while the survivors who were taken to the hospital had symptoms akin to heat exhaustion, dehydration, and heat stroke.

McManus made it clear that although the tractor-trailer was chilled, the refrigeration equipment was broken.

Additionally, he said that there was no drinking water inside the trailer.

Greg Abbott, the governor of Texas, blamed President Biden, who has been under fire for not doing enough to protect the southern border.
