3 Prison Workers Accused of Helping 'El Chapo' Escape One is a supervisor who was in charge of surveillance video By Newser Editors and Wire Services Posted Jul 25, 2015 10:30 AM CDT 21 comments Comments The tunnel used by Joaquin "El Chapo" Guzman to escape. (AP Photo/Marco Ugarte) (Newser) – A federal judge in Mexico has opened a court proceeding against three prison employees on charges they helped drug lord Joaquin "El Chapo" Guzman escape. The accused are the person in charge of the prison's video surveillance control center and two guards. The Federal Judiciary Council says there is sufficient evidence that the employees aided Guzman's escape through a one-mile long tunnel earlier this month. Prosecutors cited inconsistencies in the supervisor's statements, and the guards have no explanation for why they did not answer the telephone in their module. Four others initially arrested are in the clear, and Guzman himself remains at large.
