In Arizona, a 33-year-old Mexican woman has died while in the custody of U.S. Border Patrol. She’s the second person to die in Border Patrol custody within a week in the state of Arizona. The Pima County Office of the Medical Examiner said the Mexican woman likely died from profound dehydration and kidney failure, probably as a result of an extended journey through the desert. Immigration activists have long accused Border Patrol’s “Prevention Through Deterrence” policy of pushing migrants further and further into the deadly Sonoran Desert, where thousands of people have died or gone missing since the 1990s.
