The girl, Gurupreet Kaur, soon to celebrate her seventh birthday, was found by U.S. Border Patrol west of Lukeville, Arizona on Wednesday, when temperatures reached a high of 108 degrees Fahrenheit (42 Celsius), U.S. Border Patrol and the Pima County Office of the Medical Examiner (PCOME) said. The girl’s death, the second recorded fatality of a migrant child this year in Arizona’s southern deserts, highlighted the danger of summer heat as a surge of migrant families, mainly from Central America, cross the U.S.-Mexico border to seek asylum.
