In September 2016 , Bermúdez Zacarías presided over the tax fraud investigation of Naim Libien Kaui , the owner of Mexico City 's newspaper '' Unomásuno '' . '' Unomásuno '' and the owner 's son , Naim Libien Tella , were linked to González Valencia 's drug trafficking group the previous year . According to court documents , Libien Kaui committed an income tax fraud of MXN$ 11,413,886 in 2012 , as well as other income tax frauds in 2010 , 2011 , and 2013 . The day Libien Kaui was arrested , he issued a writ of amparo to the State of Mexico appeals court over which Bermúdez Zacarías presided . Bermúdez Zacarías , however , struck down the writ of amparo under the rationale that the case was out of his jurisdiction . He then pushed the case to another court in Mexico City . In October 2016 , he dismissed a writ of amparo issued by Gildardo López Astudillo ( alias " El Gil " ) , a major suspect in the mass disappearance of 43 students in Guerrero that occurred in 2014 . The writ of amparo was issued because El Gil wanted to be transferred from Altiplano prison . However , he rejected the request because complaints for approvals were nonexistent . Bermúdez Zacarías also presided over the cases against Javier Torres Félix , convicted high-ranking leader of the Sinaloa Cartel , and Mario Cárdenas Guillén , a suspected Gulf Cartel leader
