The FBI named a Mexican drug lord to its "Ten Most Wanted Fugitives" list, the first time an international drug trafficker ever made the roster. Juan Garcia-Abrego, whose Gulf Cartel has shipped tons of Colombian cocaine to the U.S., is under investigation for bribing a former Mexican deputy attorney general to protect his organization. That official, Mario Ruiz Massieu, is now the center of a massive corruption scandal that has shakenMexicoto the core. Ruiz Massieu's brother, a top political official, was murdered in September, allegedly in a plot masterminded by the brother of former President Carlos Salinas de Gortari. Ruiz Massieu is suspected of taking part in the murder conspiracy.TIME Mexico City bureau chief Laura Lopezsays U.S. and Mexican officials have traced up to $20 million that he stashed in banks around the U.S. since last March, and that they claim evidence of links to the cartel. "If Mario's been involved, it's been a very short time," Says Lopez. "But he made a lot of money in a very short time."
