MIT investigation maps 1,050+ migrant deaths near US border surveillance towers
A 15-month investigation finds systemic failures in the government's "virtual wall" technology, with people dying undetected near AI-enabled towers.
What to know
- MIT and Times of San Diego investigators documented 1,050+ confirmed migrant deaths near 600 US border surveillance towers over 11 years, finding systematic failures including broken equipment, failed AI detection, and unresponsive agents.
- CBP has never conducted a comprehensive audit of its surveillance tower network despite deploying them since 2015, leaving gaps in understanding where towers exist, when they were installed, and whether they work.
- No national agency collects migrant death records; investigators had to compile data from dozens of local agencies with fragmented record-keeping, making oversight impossible at federal level.
- The US plans to spend $1 billion tripling the virtual wall by 2034, even as this investigation reveals systemic failures in the current system.
“CBP does not publish a comprehensive map of its virtual wall. We instead relied on mapping work led by the nonprofit Electronic Frontier Foundation and then used satellite imagery to verify where specific towers were.”

Investigation reveals fragmented death records system prevents comprehensive oversight
The investigation found no national agency that collects and publishes all migrant death records. Texas alone required investigators to sift through thousands of pages from dozens of agencies, with records requests to local justices of the peace stalling for over a year. The lack of standardized data collection prevents CBP from effectively auditing surveillance tower performance.

An investigation found more than 1,050 people died within the advertised range of US border surveillance towers between 2015 and early 2026, including 110+ near Anduril's newest autonomous towers. Some towers have a clear sight line to as little as 10 percent of their rated coverage area. Reporting by James O'Donnell and Eileen Guo, MIT Technology…

background
Investigation confirms CBP has never conducted comprehensive audit of surveillance towers — Despite CBP installing surveillance towers since at least 2015 and having the ability to audit their effectiveness, sources told investigators the agency has never done such an audit. An internal audit would provide the complete picture currently missing, including exact tower locations, installation dates, and comprehensive effectiveness analysis.

background
Investigation documents systemic failures in virtual wall technology — The investigation finds cases of people who walked undetected through areas surveilled by advanced, AI-enabled towers and later died nearby, with bodies remaining unnoticed for weeks or months. The analysis documents broken towers, algorithms that failed to detect people, and Border Patrol agents who did not respond to alerts.

background
MIT and Times of San Diego publish comprehensive death map along border surveillance corridor — The 15-month investigation by MIT Technology Review and Times of San Diego releases a comprehensive map and analysis of migrant deaths near US border surveillance towers. The project analyzed nearly 4,000 migrant deaths, merged existing datasets from No More Deaths, Humane Borders, and the Electronic Frontier Foundation with new records from over a dozen agencies, and interviewed 45+ people including White House advisors, Border Patrol agents, and tech company employees.
