(CNN) A 2 1/2-year-old Guatemalan boy apprehended on the US-Mexico border died Tuesday night in El Paso, Texas, the Washington Post reported.

The child had been in the hospital in US custody for several weeks after crossing into the US with his mother, the Post reported, citing Guatemala Consul Tekandi Paniagua and another source.

CNN has reached out to the Department of Homeland Security and the Guatemalan consulate in Del Rio, Texas, but hasn't yet received a response.

The boy would be the fourth Guatemalan child since December to die after a border apprehension.

Jakelin Caal Maquin , 7, died of sepsis, a bacterial infection, in an El Paso hospital in December, two days after she and her father were detained. Weeks later, Felipe Gómez Alonzo , 8, died of flu complicated by sepsis while in Customs and Border Protection custody.
