The Health and Human Services Department has confirmed the death of an unaccompanied migrant child who had been in its custody since May. A 15-year-old migrant girl from Guatemala, whose name has not been released, died Monday of multi-organ failure at a hospital in El Paso, Texas. She reportedly suffered from an underlying illness. She’s the fourth migrant child to die in U.S. custody this year, as officials have been accused of severe medical neglect and other abuses.
