Like a marathoner at the end of a grueling race, 16-year-old Jorge Romero sits on the grass, exhausted. A county constable has detained him about a hundred yards from the Rio Grande.
For a month, Romero traveled from El Salvador through Mexico to Texas, avoiding predatory police and gangs, warding off mosquitoes and hunger.
Migrants like Romero are creating a humanitarian crisis for federal border authorities. Record numbers of Central American immigrants are crossing the Rio Grande into South Texas, overwhelming the Border Patrol's limited holding facilities.
