MIT Technology Review maps deaths along the US border's AI 'virtual wall,' finding systemic surveillance failures as CBP plans a $1 billion expansion

MIT Technology Review published an investigation on 2026-09-21 into deaths occurring near the US border's AI-enabled 'virtual wall' surveillance towers, creating the first comprehensive map of such deaths. The investigation found systemic flaws: in multiple cases, towers failed to detect migrants, or agents failed to respond to alerts the system generated. The report calls for a comprehensive audit of the surveillance network and improved death tracking, noting these findings come as CBP plans to spend $1 billion to triple the virtual wall's size by 2034. The methodology involved analyzing thousands of pages of government documents and conducting more than 45 interviews; AI (Anthropic's Claude) was used to process some police records, but human verification was required due to data inconsistencies. Public records requests were reportedly difficult because of inconsistent data protocols across agencies.
