<p>The allegations are made by Vicente Zambada-Niebla, a top ranking cartel boss extradited to the U.S. last year on drug charges. He is a close associate of Mexico's most wanted man, Joaquin "El Chapo" Guzman and the son of Ismael "Mayo" Zambada-Garcia. </p>
<p>Both remain fugitives, in part, because of the deal Zambada- Niebla made with the U.S. Drug Enforcement Agency, according to a defense motion filed last Friday in the case.</p>
<p>Alvin Michaelson, the Los Angeles attorney representing Zambada- Niebla who wrote the brief, refused comment.</p>
<p>The deal allegedly began with Humberto Loya-Castro, a Sinaloa cartel lawyer who became an informant for the D.E.A. after a drug case against him was dismissed in 2008. </p>
