Migrants from Latin America trying to cross the U.S. border always risk their lives during the journey. Many are often robbed, raped or physically wounded over the course of the trek. But crossing illegally into the United States from Mexico can be deadly as well.
In the past 25 years U.S. Border Patrol has found the bodies of 7,000 migrants from Mexico. Most of them died from either heat exhaustion or by drowning.
Many carried no identification so next-of-kin could not be contacted.

Mexican authorities encourage citizens throughout Mexico to come forward with information they may have to help identify border-crossers who’ve perished along the U.S. Mexico border.
