The boy, who was not immediately identified, is the fourth Guatemalan child known to have died after being apprehended at the border since December, CNN reported.

Tekandi Paniagua, the consul for Guatemala in Del Rio, Texas, told The Associated Press and The Washington Post that the boy came into the U.S. through El Paso, Texas, in early April with his mother. It was not immediately clear when the boy fell ill, though an official speaking on the condition of anonymity told the Post his mother alerted Border Patrol agents to his health April 6. The official said he was taken by ambulance to a hospital in Horizon City later that day and later transferred to Providence Children's Hospital in El Paso.
