Arizona-Mexico Border Sees Record Migrant Deaths in July 2023

Tragedy Strikes at the Arizona-Mexico Border as July Sees Unprecedented Migrant Deaths

In July, the Arizona-Mexico border experienced a somber milestone, recording the highest number of migrant fatalities in two years. A recent report from Humane Borders, a nonprofit organization, documented the discovery of 19 bodies within the month, underscoring the perilous conditions faced by migrants traversing the harsh desert landscape.

Humane Borders partners with the Pima County Medical Examiner's Office to meticulously track these fatalities. Their data indicates that a considerable number of those who perished were found to have died shortly before being discovered, indicating that treacherous conditions persist despite narratives surrounding border security.

Brad Jones, a political science professor at the University of California, Davis, and a board member of Humane Borders, commented on the situation, stating, “There’s this narrative that… the border is effectively closed — that nobody is crossing. Well, this is pretty clear evidence that, not only are people crossing, like crossing recently, within the last few months, but also dying.” This highlights the ongoing danger migrants face, particularly during the sweltering summer months.

The report details that within the 19 found, five individuals had been dead for less than 24 hours, while two had been deceased for fewer than seven days, and four for under three months. The combination of high temperatures and seasonal monsoon rains exacerbates the risks associated with such journeys.

Despite strict immigration enforcement policies established during the Trump administration that have effectively restricted the asylum application process, many migrants remain undeterred. Although immigration officials are reporting low apprehension rates, the death toll continues to rise.

Jones warns of the alarming implications of these trends, remarking, “Which is of concern, because it leads me to think that, however risky it is to cross through the Arizona desert in a normal year, it’s even more risky and dangerous these days.” He emphasizes that increased border security has historically failed to dissuade individuals from migrating. “The notion that the border is fully closed is always an illusion. If there’s an existential need, or an existential push for migrants or asylum seekers to leave where they’re at, some are going to make the attempt to come here,” he added.

In 2023, the number of remains discovered in Arizona has reached 73 by this point in the year, an increase from 59 in the same timeframe last year. With a total of 103 deaths recorded throughout 2025, the current trajectory suggests that this year's total may exceed previous years. Over the past quarter-century, Humane Borders has documented more than 4,500 deaths along the Arizona-Mexico border, marking a continued humanitarian crisis in the region.
