MEXICO CITY: A court in Mexico on Monday formally charged four criminal justice workers for their alleged role in the July prison escape of drug kingpin Joaquin “El Chapo” Guzman. Two of the men charged were prison employees tasked with video monitoring of El Chapo’s cell. The other two worked for the Mexican intelligence service. Three other workers were charged several weeks ago with aiding Guzman, 58, in his daring prison escape. Guzman managed to flee the Altiplano maximum-security prison outside Mexico City, just 17 months following his capture after years on the run. He slipped out of his cell through a 1.5-kilometer tunnel dug under his private shower in the prison some 90 kilometers west of Mexico City, and has vanished without a trace.
