On Sept. 14, 2025, 30-year-old Graciela Gómez Hernández crossed from Tijuana into Southern California and sent voice messages to her family as she walked. Weeks later her skeletonized remains were found in the Otay Mountain Wilderness—within sight of federal surveillance towers that patrol the border.
What happened
Gómez Hernández told her family only the day before that she intended to cross; she hoped to work in the U.S. and send money to her three children and her parents. She paid about 20,000 pesos (roughly $1,150) to smugglers for guidance but walked without a guide through steep, brush‑covered terrain.
Between about 2 and 3 p.m. on Sept. 14 she sent a final voice message saying, “I can’t do it anymore.” Her remains were discovered on Oct. 4, 2025. Jennifer Wright, the medical examiner, reported finding skeletonized female remains approximately 100 yards north of the international border. The body had decomposed and scavengers had disturbed the scene; no water or food was found nearby, so the examiner could not definitively determine whether death resulted from dehydration or foul play.
After DNA confirmation, Gómez Hernández’s family paid more than $4,000 to repatriate her bones to Mexico, where a funeral was held nine months later.
Surveillance in view of the death
From the location where Gómez Hernández’s body was found, a slender gray surveillance tower was visible about one mile away. The nearby tower—manufactured by General Dynamics and in place since 2019—has electro‑optical and infrared cameras with long‑range lenses that manufacturers say can track targets 5–7 miles away. A second, newer Anduril tower sat about 1.4 miles away on another ridge; that system uses AI to classify and prioritize moving objects.
The Otay Mountain Wilderness and the surrounding borderlands are monitored by an interconnected array of sensors: mounted trail cameras, underground motion detectors, radar, infrared sensors, drones and blimps. The Electronic Frontier Foundation’s field research and documents show more than 120 towers along the California border. The Government Accountability Office reported in June 2026 that Customs and Border Protection (CBP) had 803 fielded towers, planned 175 more, and that the initiative’s cost was estimated at $1.4 billion; policymakers expect additional funding from the 2025 One Big Beautiful Bill Act, and CBP projects as many as 2,300 towers by 2034.
Patterns of deaths near cameras
Journalistic analyses by Times of San Diego and MIT Technology Review found a troubling pattern: from 2022 through 2025 at least 138 people died within the nominal range of a nearby surveillance tower in California. A topographical review estimated that more than half of those remains were found in spots where a camera would likely have had an unobstructed line of sight; another analysis concluded at least 81 of those people were probably within a tower’s field of view.
Some migrants die quickly—falls from the border fence or drownings—but dozens suffer slow deaths from exposure in remote wilderness that might have been prevented with timely rescue or medical aid.
System limitations and maintenance issues
The proximity of so many deaths to high‑resolution cameras raises two possibilities: the systems failed to detect people in distress, or the systems detected them but authorities did not respond. There are documented operational problems. An internal October 2024 memo obtained by NBC News indicated roughly 30% of older, operator‑monitored towers were broken or missing parts. A March 2026 military report noted operational challenges with certain G‑BOSS(E) military towers deployed in Otay Mountain Wilderness—including tipping, rodent damage, battery failures and camera zoom malfunctions caused by transport shocks.
Manufacturers and some officials promote towers as life‑saving: Anduril said in 2024–2026 that its installations have “autonomously identified hundreds of thousands of border crossings,” and a CBP sector chief in 2026 said the agency was “dang close to pretty much knowing everything that comes across.” Yet local search‑and‑rescue leaders and advocacy groups question practical effectiveness in rugged terrain and point to limited agent resources that constrain search and rescue.
Local accounts and operational tradeoffs
Volunteer searchers and aid groups describe a tension between surveillance presence and actual rescue outcomes. Cesar Ortigoza (Armadillos) and Rafael Hernández Larraenza (Desert Angels) report rescuers frequently find dehydrated people in remote canyons who say they called for help but received no response. Bryce Peterson of No More Deaths compiles autopsy reports and argues rescue is not always prioritized when agents encounter single migrants versus larger groups.
Analysts have also noted a deterrent effect: towers can push migrants into longer, more dangerous routes to avoid surveillance, or cause smugglers to send people across singly to overwhelm the system with many individual targets, creating more alerts than agents can investigate.
Could the towers have seen Gómez Hernández?
It is possible the towers captured footage of her; it is also possible they did not. Terrain, vegetation, or equipment downtime could have blocked or disabled views. The Border Patrol did not respond to questions about whether the tower visible from the site was operational or whether it detected Gómez Hernández before she died. Anduril did not answer questions about tower performance in mountainous terrain; General Dynamics referred questions to the Border Patrol.
Aftermath and broader implications
Gómez Hernández’s case is one among hundreds that researchers and advocates say illustrate limits of a surveillance‑centric border strategy. Even as technology and AI‑enabled sensors proliferate—supplemented in 2025 by a Defense Department directive to use satellites—maintenance gaps, terrain constraints and human resource limits complicate the capacity to detect and respond to people in distress.
Local volunteers maintain water drops and leave supplies along trails, and they continue to find evolving migration patterns. Search‑and‑rescue teams receive daily calls from families searching for missing relatives. Advocates warn that expanding surveillance without commensurate rescue capacity may increase risks by pushing migrants into more dangerous paths or encouraging speedier, riskier movement that reduces opportunities to drink and rest.
While the presence of towers is promoted as enhancing situational awareness and deterrence, investigators and local rescuers say the technology alone has not prevented deaths such as Gómez Hernández’s—and that the policy tradeoffs may be contributing to more perilous crossings.
Sources and methodology
The reporting draws on the San Diego County Medical Examiner’s report, interviews with family members, search‑and‑rescue volunteers (Armadillos, Desert Angels), advocacy groups (Border Angels, No More Deaths), and public records. Times of San Diego analyzed death locations relative to tower positions and confirmed tower installation dates via satellite imagery and field checks. MIT Technology Review conducted a topographical analysis assessing likely unobstructed camera sightlines for a subset of recent cases.
