Border Surveillance Failures: The Tragic Death of Graciela Gómez Hernández

She had only walked for a couple of hours, and already she was lost. On the afternoon of Sept. 14, 2025, 30-year-old Graciela Gómez Hernández crossed the border from Tijuana into Southern California, sending voice messages to her mother and sister as she walked. This story is part of "Dying on Camera," a collaboration between MIT Technology Review and Times of San Diego. Journalists spent the past year examining the failures of border surveillance technology and uncovering the stories of those who die in the borderlands. Gómez Hernández informed her family of her plan only the day before. Upon arriving in California, she hoped to work and send money back to her parents and three children in southern Mexico, including her 11-year-old son who had asked for a bicycle. She either climbed a ladder over the border wall or slipped through a section of steep terrain where fencing had not yet been built. This marked the first segment of a hike through the Otay Mountain Wilderness. While the eastern edge of San Diego is only a mile away, many migrants hike 10 to 20 miles north through the mountains to evade Border Patrol, aiming for smaller towns and distant highways with fewer checkpoints. Between 2 and 3 p.m., Gómez Hernández sent a final message to her mother, whispering, "I can’t do it anymore." By the time a forensic crew collected her body two weeks later, much of it had disappeared into the earth. Though she died alone, she was in one of the most heavily surveilled strips of land in the world. Before her death, she told her family via WhatsApp that she could see helicopters overhead and white Border Patrol trucks making periodic laps on the road below, even if no agents saw her or knew she was there.
