The report, marked “sensitive but unclassified,” had been updated on Friday, suggesting that Jakil Caal Maquin, 7, was counted among those four December deaths counted by border authorities.
The figure represents migrant deaths recorded by border officials within their area of responsibility and is not exclusive to people in U.S. custody.
For example, 50 deaths in 2018 are marked as “water-related,” presumably people who drowned trying to cross sections of the border marked by rivers. Exposure to heat was attributed to the largest number of deaths.
The figures paint a grim picture for the caravans of migrants making their way to the U.S. border.
This week, the death of Maquin sparked an uproar among congressional Democrats and advocacy groups.
U.S. Customs and Border Protection confirmed Friday that the Guatemalan child died shortly after turning herself in with her father at a remote New Mexico border crossing.
A total of 281 deaths were counted in the 2018 budget year, which ended Sept. 30, according to the document. Since then, another 32 people have been found dead -- a figure that includes the four in December.
The document states that the vast majority of deaths in the recent budget year -- 117 -- were migrants from Mexico. Another 116 people were “unknown.” It counts 19 people who died in 2018 from Guatemala, 14 from Honduras and eight from El Salvador.
The document notes that the numbers are “preliminary and subject to change.”
