(CNN) An 8-year-old migrant's last days were a blur of border patrol stations and hospital visits in a location about 2,000 miles from his family's home in Guatemala.

The boy's death while in the custody of US Customs and Border Protection comes just weeks after a 7-year-old Guatemalan girl died while being held by CBP. He was identified as Felipe Alonzo-Gomez by US Rep. Joaquin Castro, but CBP did not name him.

The children's deaths have highlighted the life-and-death challenges that migrants face in attempting to come to the US and caused CBP to announce several policy changes around its care of children under 10 years old.
