The Disappeared report series is collaborative project between two Tucson-based organizations, La Coalición de Derechos Humanos and No More Deaths. Between Derechos Humanos’ 20 years of community work, including the 24-hour Missing Migrant Crisis Line, and No More Deaths’ 12 years of humanitarian aid in the Arizona backcountry, we have witnessed and listened to thousands of stories of border crossings throughout Southern Arizona. Our research goals are transformative: to expose and combat those US government policing tactics that cause the crisis of death and mass disappearance in the borderlands. This report details the intentional destruction of over 3,000 gallons of water left out for border crossers, implicating the US Border Patrol in the majority of this destruction. We document how Border Patrol agents engage in the widespread vandalism of gallons of water left for border crossers and routinely interfere with other humanitarian aid efforts in rugged and remote areas of the borderlands.
