Undocumented immigrants: Faces of the displaced

Silvia Perez, 29, from Chiapas, Mexico spends a night at the San Juan Bosco shelter for undocumented immigrants in Nogales, Mexico, March 9, 2013. She said she was abandoned in the desert by the "coyote" who she paid to bring her across the border into Arizona. She said she was then picked up by U.S. immigration agents and deported. She plans to try again to reach the United States.
