YUMA, AZ (AZFamily) — Despite a substantial drop in overall migrant crossings along the U.S.-Mexico border, humanitarian organizations and medical examiners are reporting a stark and troubling paradox: the number of deaths in the desert is rising, and the geographic locations of those fatalities are shifting.

Experts say the deadly toll is increasingly concentrating in the rugged, unforgiving desert of southwestern Arizona, bringing the crisis directly into the backyard of the Yuma community.
“This notion that the border is sealed off is just simply not the case,” said Dr. Brad Jones, a researcher and death-mapping expert with the humanitarian organization Humane Borders. “If that were the case, we would see next to zero recent deaths, and that is not what we are seeing.”
According to data compiled by Humane Borders, search teams and authorities have recovered the remains of at least 75 migrants in the Arizona desert so far this year. At this same point last year, that number stood at 59.
Jones expects the grim tally to rise steadily, threatening to surpass the 103 total deaths recorded in the region for all of 2025. The most hazardous months of the year still pose threats.
“June, July and August, and then followed by September—guess what, those are the hottest months,” Jones said. “And if they’re not hot, because the monsoons come… monsoons bring terrible flooding.”
While federal authorities point to tougher enforcement and asylum restrictions as a successful deterrent to lower crossing statistics, human rights advocates argue these policies do not stop desperate people from attempting the journey. Instead, they say, increased security simply funnels migrants toward much more dangerous, isolated routes.
“While tougher border policies may temporarily slow the flow, enforcement does not stop migrants entirely,” Jones said. “Instead, these tough rules only push desperate people to take even deadlier risks and paths to cross into the U.S.”

For those who navigate these extreme corridors, the consequences of a single misstep can be fatal.
“You die one of the most horrific deaths that you can die, which is exposure in the desert,” Jones said, urging the public to look past the political rhetoric. “That’s how I hope people would choose to think about the death data—not just as data points, but as real human beings.”
The official figures underscore the daily tragedy unfolding just miles from local communities. In July 2026 alone, the Pima County Office of the Medical Examiner reported 19 migrant deaths.
However, experts emphasize that official counts only represent a fraction of the reality. Because of the vastness of the southwestern terrain, search teams are constantly recovering older remains of individuals who succumbed to the elements months or even years before being found.
