The remains of 19 people were found in the Arizona desert in July, making it the deadliest month recorded along that stretch of the border in two years, according to data from the Pima County Office of the Medical Examiner and the humanitarian group Humane Borders. Among the dead were children.
The July figure, first reported in detail by The Guardian and confirmed by Humane Borders and several Arizona news outlets, pushed the number of remains recovered in southern Arizona this year to 73 — already ahead of the 59 found by the same point in 2025, a year that ended with 103 recorded deaths.
Over the past 25 years, the two organizations have documented more than 4,500 deaths in the region, a toll they describe as one of the most lethal and closely tracked migration corridors anywhere in the world.
What makes the numbers striking is the context.
Federal data show that apprehensions along the southwest border have fallen to historic lows under the current administration’s enforcement and asylum policies. Yet the death count is rising, not falling, a pattern that researchers who study the border say has held for decades: as crossing is pushed away from established checkpoints, the people who still attempt it are funneled into deadlier terrain.
Brad Jones, a political science professor at the University of California, Davis, and a board member of Humane Borders, said the July deaths were mostly recent rather than long-buried remains newly uncovered. He rejected the idea that tougher enforcement has sealed the border off. “The notion that the border is fully closed is always an illusion,” Jones told the Arizona public radio station KJZZ, adding that people facing an urgent enough threat at home will keep trying to reach the United States regardless of the risk.
Summer is the deadliest season in the Sonoran Desert, where temperatures routinely climb into the triple digits.
The most common causes of death are dehydration and heat exposure, though the medical examiner’s records also attribute deaths to hypothermia in colder months, drowning during monsoon flooding, blunt-force trauma, and causes that are never determined.
Octavio Fuentes, the executive director of Humane Borders, a Tucson-based group that maintains water stations across the desert and partners with Pima County to map deaths, said the heat leaves migrants with no margin for error. People “simply can’t carry enough water to survive,” he said in the group’s data release, calling it a preventable way to die. A breakdown of the July cases underscored how recent many of the deaths were: several of those found had died within a day, and others within a week.
Researchers are convinced that the recorded figures capture only a fraction of the dead.
The Arizona border spans roughly 400 miles, much of it remote desert, and remains are often discovered by chance, by a hiker, a rancher, a Border Patrol agent, or a volunteer.
In that vastness, bodies can be lost to the elements and to scavenging animals within a short time, leaving no trace.
Jones has estimated that the actual number of deaths could run several times higher than what is documented. The scale of the uncertainty is visible in the identification data alone: as of July, more than 1,600 sets of recovered remains in the database remained unidentified. To convey the magnitude, Jones has likened the accumulated deaths to a passenger jet full of people crashing in the desert every summer for more than two decades — a disaster that, spread out in ones and twos across the sand, never produces the alarm a single crash would.
The persistence of the crossings, even as they grow more dangerous, sits at the center of Amelia Frank-Vitale’s research. An anthropology professor at Princeton University and the author of “Leave If You Can: Migration and Violence in Bordered Worlds,” Frank-Vitale studies what drives people to gamble their lives on routes through deserts and jungles like the Darién Gap between Colombia and Panama. Often, she has found, they do not feel they have a real choice.
She has described meeting a pregnant woman in Honduras who was preparing to migrate even as the crackdown on immigrants dominated international headlines, concluding that reaching the United States was still her best option. Frank-Vitale argues that Washington has never fully reckoned with its own role in destabilizing the countries whose citizens now seek refuge — and notes that even before the asylum system was largely shut down, only a small share of applicants from Central America and elsewhere were ever granted protection.
The shift in border policy has been sweeping. The CBP One app, once used to schedule appointments for asylum seekers, has been repurposed by the administration to encourage “self-deportation,” and rules requiring many asylum seekers to wait in Mexico while their cases proceed have been revived. Fuentes traces the deadly logic further back, to the “prevention through deterrence” strategy adopted in the 1990s, which deliberately made crossing at safer, more visible points difficult and, in his view, has pushed desperate people into the open desert ever since.
The result, advocates say, is a border that appears quieter in the enforcement statistics but is exacting a rising human cost out of public view. The bodies recovered in July — men, women, and children who died within reach of a country they were trying to enter — are, by every expert account, only the portion of the toll that happened to be found.
