How we made the first comprehensive map of deaths along the US border’s “virtual wall”
A 15‑month study mapped 4,000+ migrant deaths near US border towers, revealing gaps in surveillance and record‑keeping.
Why Now
MIT Technology Review’s investigative piece, part of the Dying on Camera series, released after a year‑long data hunt into border deaths and tower locations.
What Happened
The team merged datasets from No More Deaths, Humane Borders, EFF, and new records from 17 Texas counties, covering 2015‑2026. They used AI (Claude) to parse sheriff reports and manually verified coordinates, ending up with ~4,000 confirmed death sites near surveillance towers.
Why It Matters
The map shows that many deaths occur right where towers are supposed to enable rapid response, highlighting failures in technology and data transparency. It underscores the need for better record‑keeping and accountability in border enforcement.
The Limitation
The analysis undercounts Texas deaths because it relies on sheriff records, excludes deaths handled by police, and depends on incomplete or delayed public records.
What You Can Do
