Under tight security in Chicago’s federal courthouse, a son of Joaquin ‘El Chapo’ Guzman pleaded not guilty Monday to sweeping narcotics trafficking charges alleging he helped lead the notoriously violent Sinaloa cartel after his father’s arrest seven years ago.

       Dressed in an orange jail jumpsuit and shackled at the ankles, Ovidio Guzman Lopez, 33, listened to the proceedings through a Spanish interpreter, though he occasionally answered U.S. District Judge Sharon Johnson Coleman’s questions in heavily accented English.

       Prosecutors said one of the five counts Guzman Lopez is charged with carries a mandatory life sentence if convicted. The death penalty was taken off the table as part of a negotiation for Guzman Lopez’s extradition with Mexican authorities, according to prosecutors.
