Migrant Camp Mexico 11-17-19 AP.jpeg

In this Oct. 11, 2019 photo, migrants get free haircuts by volunteers at a migrant camp near a legal port of entry bridge in Matamoros, Mexico. Tamaulipas became a bloody emblem of the problem of violence against migrants in 2010 when 72 migrants were found slain at a ranch in San Fernando, and a year later when the bodies of 193 migrants were found in the same area in clandestine mass graves, apparently murdered by a cartel to damage a rival’s people-smuggling business.
