HOUSTON (AP) – U.S. Customs and Border Protection ordered medical checks on every child in its custody Tuesday after an 8-year-old boy from Guatemala died, marking the second death of an immigrant child in the agency’s care this month.

The death came during an ongoing dispute over border security and with a partial government shutdown underway over President Donald Trump’s request for border wall funding.

The boy, identified by Guatemalan authorities as Felipe Gómez Alonzo, had been in CBP’s custody with his father, Agustin Gomez, since Dec. 18. CBP said in a statement late Tuesday that an agent first noticed the boy had a cough and “glossy eyes” at about 9 a.m. Monday. He was eventually hospitalized twice and died just before midnight, the agency said. CBP earlier said that the boy died just after midnight.
