A man whose slain brother led one of Mexico’s most powerful and violent drug cartels pleaded guilty Friday in Washington to conspiring to traffic cocaine and methamphetamine into the U.S.
Antonio Oseguera Cervantes worked for cartels with his brother Nemesio Rubén Oseguera Cervantes, the drug lord known as “El Mencho” who was killed by the Mexican army in February, according to federal prosecutors.
