US immigration authorities say an 8-year-old boy from Guatemala has died in government custody

The Department of Homeland Security says it has completed new medical screenings of almost all the children in the care of the U.S. Border Patrol.

The screenings were ordered after an 8-year-old child died in the custody of U.S. Customs and Border Protection. The boy, identified by Guatemalan officials as Felipe Gomez Alonzo, was the second migrant child to die in CBP's custody this month.

The department said Wednesday some children detained in more remote areas were re-screened by emergency medical technicians or Border Patrol agents. In other places, some children were taken to medical facilities. DHS wouldn't say exactly how many children are in Border Patrol custody.
