An investigation by MIT Technology Review and the Times of San Diego has identified a significant gap between the intended function of US border surveillance technology and the reality of migrant deaths in the borderlands. Despite billions of dollars invested in a "virtual wall" of AI-enabled towers, drones, and sensors, the report found that more than 1,050 people died within the operational range of these surveillance systems between 2015 and early 2026.

The study, which cross-referenced nearly 4,000 locations of human remains with data on approximately 600 surveillance towers, indicates that these fatalities are not isolated incidents. Researchers discovered that deaths occurred within the advertised range of nearly two-thirds of the towers analyzed. Even among the most modern autonomous towers manufactured by Anduril, which utilize AI to detect and track movement, at least 110 deaths were recorded within their vicinity since 2021.

The investigation highlights the case of José Morales Bernal, who died of environmental exposure in April 2024. Despite being within range of three AI-equipped towers, his presence went undetected by Border Patrol until landfill workers discovered his body hours later. Records show that 18 other individuals died in that same desert stretch during the same year.

While US Customs and Border Protection (CBP) maintains that these towers enhance situational awareness and agent safety, the report suggests a lack of internal oversight. Former and current officials noted that the agency does not formally investigate whether surveillance systems failed to detect individuals or why agents did not respond in time to prevent fatalities. An Anduril spokesperson stated that the company delivers the technology but that operations are managed by CBP, noting that environmental factors and specific agency settings can impact tower performance.

The findings have drawn criticism from lawmakers, including Representative Delia Ramirez, who questioned the efficacy and transparency of the program. With federal plans to expand the network to nearly 1,500 additional towers by 2034, the investigation raises critical questions about the reliance on technology to address the complex humanitarian and security challenges of the southern border.
