Texas says there is "no evidence" of wrongdoing after mass graves filled with bodies of immigrants were found miles inland from the U.S.-Mexico border. The bodies were gathered from the desert surrounding a checkpoint in Falfurrias, Texas, in Brooks County. An investigation was launched after the mass graves were exposed last November in a documentary by The Weather Channel in partnership with Telemundo and The Investigative Fund. The report also found many of the migrants died after crossing into the United States and waiting hours for Border Patrol to respond to their 911 calls. We speak with reporter John Carlos Frey, who found rampant violations of the law.
