TUCSON, Ariz. (13 News) – Migrant deaths in the Southern Arizona desert spiked to their highest summer levels in two years, according to new data released by humanitarian group Humane Borders and the Pima County Office of the Medical Examiner.
Advocates warn that despite increased border enforcement, extreme summer temperatures are proving deadlier than last year.
Key Takeaways
- Surge in Fatalities: 19 migrant deaths were recorded in July and 13 in June, marking the highest monthly totals in two years.
- Year-to-Date Count: 73 individuals have died so far in 2026, compared to 59 at this time in 2025.
- A Deadly Milestone: Over the last quarter-century, at least 4,505 migrants have lost their lives in Southern Arizona.
According to medical examiner data:
- Five of the individuals recovered in July had been dead for less than 24 hours.
- Dehydration and exposure remain the primary causes of death, though hypothermia, drowning, and blunt force trauma are also documented.
- Most remains are recovered by volunteer search and rescue groups, Border Patrol agents, hikers, and local landowners.
