In this Aug. 27, 2014 photo, a migrant rests in a near-empty migrant shelter in Ixtepec, Mexico. A Mexican crackdown seems to be keeping women and children off the deadly train, known as “The Beast,” that has traditionally helped thousands of migrants head north. It is a far cry from the wave of migration that pressed toward the U.S. earlier this year, spurred on by a surge in violence in several Central American countries and news that women and children who reached the United States were being let go inside the country with orders to return for immigration hearings because family shelter space had filled up.
