Of these, about three-quarters – nearly 10,000 – have been detained in the Border Patrol’s Yuma sector, a 202 km (126 mile) expanse of desert and rocky mountains that stretches from California’s Imperial Sand Dunes to the border between Arizona’s Yuma and Pima counties. In 2019, a six-year-old Indian citizen from the Punjab was found dead near the Arizona town of Lukeville in a high-profile case.
