The former national leader of the Mongols motorcycle gang has been sentenced in a case that accused members of murder, drug trafficking and violent attacks. Ruben Cavazos pleaded guilty to one count of racketeering conspiracy in January 2009. The results from his sentencing hearing held Thursday were sealed, according to an online docket. Thom Mrozek, a spokesman for the U.S. attorney's office declined comment Friday. A message left for deputy federal public defender John Littrell was not immediately returned. Prosecutors say Cavazos ordered members to engage in murders, extortion and drug trafficking. They say he was responsible for brokering a deal with the Mexican Mafia over the collection of drug payments in areas controlled by that gang. Most of the 79 members indicted have pleaded guilty to a variety of charges.
