The woman, who is believed to be part of the group, was found unresponsive and could not be resuscitated, the agency said. San Diego took custody of her body after responding to the area.
“This is another example of the relentless tactics used by smuggling organizations to boost their power and profits.” San Diego Sector Chief Patrol Agent Aaron Heitke said in a written statement. “We will work tirelessly to pursue and bring to justice those responsible for this tragedy.”
The agency said it had arrested 36 Mexican citizens who were swimming across the border, including 13 who were rescued from the water by the U.S. Coast Guard. All 36 were taken to the border station for processing.
But the numbers do not represent all the deaths of migrants at the borders, as state and local agencies can find the bodies without the involvement of the border patrol, which means the death toll is likely to be higher.
Most of the deaths of migrants at the borders were related to exposure to heat, the agency reported. Migrants often face dangerous terrain and can get lost when trying to break into the US.
