Oscar Nava Valencia, a Milenio cartel drug smuggler, on Monday testified in a New York federal court that he paid off Mexico’s former security secretary Genaro GarcÃa Luna, accused of receiving bribes from the Mexican Sinaloa cartel. Nava Valencia told jurors that he bribed Mexican high-ranking government officials that include GarcÃa Luna with $5 million to secure massive drug shipments containing 10 tons of cocaine. Nava Valencia also testified that GarcÃa Luna, in return, provided him with a document claiming that the U.S. was aware of the cocaine.
