A man accused of taking part in a scheme to smuggle teenagers into the U.S. and force them to work at an egg farm for little pay is in custody after being arrested at the Mexican border, federal prosecutors announced. The teens from Guatemala were kept as virtual slave laborers, forced to turn over most of their earnings, and had to live in run-down trailers with no heat and little food before they were rescued in 2014, investigators have said.Six others already have been convicted in the case, which prosecutors said involved luring the boys and young men with promises of enrolling them in school and finding them good jobs. The indictment said Trillium Farms paid about $6 million to Duran Ramirez and one other unnamed person.The charges against Duran Ramirez include forced labor, conspiracy and encouraging illegal entry. He is scheduled to appear in a federal court in McAllen, Texas, on Friday. An attorney for Duran Ramirez declined to comment on the case Thursday.
