TUCSON, Ariz. — In the vast expanses of the Arizona desert where scorching summer temperatures often surpass 110 degrees Fahrenheit, each day presents a critical opportunity for rescue teams like Capellanes del Desierto (Desert Chaplains) to save lives. Led by evangelical pastor Oscar Andrade, this organization dedicated to search-and-rescue efforts often encounters migrants suffering from dehydration or hypothermia – the perilous extremities of desert weather that can prove fatal without proper intervention.
“For four years now, we’ve been operating across California, New Mexico, Texas, and Arizona,” said Andrade, who noted his group has rescued 362 people and discovered 183 bodies to date. These unsettling figures underscore a broader issue prevalent along the U.S.-Mexico border, where insufficient data recording masks the true magnitude of migrant deaths. This lack of reliable data complicates efforts to address what many describe as a growing humanitarian crisis.
Research conducted by the University of Arizona’s Binational Migration Institute highlights these discrepancies. According to their findings, the Pima County Medical Examiner’s Office in Arizona reported 565 more migrant deaths from fiscal year 2000 to 2022 than were recorded by Border Patrol. This gap, roughly amounting to a 17 percent difference in reported deaths, suggests an undercounting of fatalities.
“The true scale of this tragic situation is likely much bigger than we understand,” said Daniel Martinez, sociology professor and co-director of the Binational Migration Institute. “Each statistic represents a human being who was someone’s family member, which amplifies the tragedy.”
Amid these challenging circumstances, the changing profile of migrants has also shifted significantly. “Historically, young Mexican men traveled primarily for work. Now, we’re seeing increasingly diverse groups including women, children, and families from various countries seeking asylum,” explained Martinez.
An investigation in June by Noticias Telemundo revealed in California, Arizona, New Mexico, Texas, and Florida, over 1,500 undocumented individuals were in morgues and cemeteries awaiting identification. Arizona alone accounted for 1,388 of these unidentified cases, highlighting the challenges local forensic authorities face in keeping pace with the continuous influx of cases.
The dangers these migrants face are compounded by policies and criminal activities that obscure their fates. “Cartel leaders often instruct coyotes not to reveal where migrants die, preventing recovery efforts,” Andrade explained. He believes over a thousand cases of unrecovered remains exist, further complicating the already dire situation.
Government responses and border security measures add another layer to this complex issue. Following the end of a specific border security initiative in 2012, which tasked Border Patrol with actively searching for migrant deaths, the agency now only reports deaths they encounter directly in their daily operations, potentially overlooking many others.
Looking forward, Arizona’s new ballot measures approved during the last election will increase local law enforcement’s authority over immigration matters, intensifying penalties for various immigration-related infractions. Andrade fears this might drive migrants into even more perilous routes, increasing the odds of fatalities.
Meanwhile, local forensic capabilities in Arizona have expanded with the recent opening of a new 35,000-square-foot facility in Pima that features advanced autopsy and laboratory equipment—resources crucial for addressing the high caseload of migrant deaths. “We urge families of the missing to reach out. We have personal belongings and documents that could help identify them,” said Gene Hernandez, supervisor of medicolegal death investigators in Pima County. “Compliance helps us more than silence.”
Despite the perilous landscape that Mexican and Central American migrants face, the mission of organizations like Capellanes del Desierto remains unwavering. “We are improving our readiness to respond more effectively,” stated Andrade. His commitment and that of his team signal a continued effort to mitigate the grim realities facing migrants in one of the world’s most dangerous migration corridors.
