In an investigation for Texas Monthly, Aaron Nelsen dug into what is – and isn’t – known about migrant deaths along the U.S./Mexico border. He reported that U.S. immigration policy has intentionally funneled migrants into dangerous crossing areas for decades, to deter them from making the journey, and experts estimate that thousands have drowned in the Rio Grande River. It’s impossible to know how many have died in the river or elsewhere along the border because of how federal and state authorities in the U.S. and their counterparts in Mexico report and handle incidents. With support from the Fund, Nelsen spent a year reporting the story.
