Lukeville, Arizona— A human skull sits under the sweltering sun near the Mexican border on July 3. Due to extreme temperatures, the summer months are always more perilous for migrants. But this year, the number of dead among people who have crossed the border is way up across the state, compared with the same period in 2016. This increase comes as the U.S. and Mexico continue to bicker over a proposed border wall—and as American authorities are apprehending fewer and fewer migrants trying to cross. As Chelsea Halstead of the Tucson-based Colibrí Center for Human Rights told The Arizona Republic: “Less people are crossing, and more people are dying.”
