In 1998, Border Patrol found one dead migrant for every 5,767 apprehensions, but after building the fences and doubling its force, it found one dead migrant for every 1,034 apprehensions in 2017. That’s a sign that the journey is now about 5 times more dangerous. In addition, the remoteness of the locations where they were apprehended contributed to the deaths of both children who died in Border Patrol custody in recent weeks, as it was more difficult for them to get help.
