(AP Photo/Eduardo Verdugo,File) (Newser) – A federal judge in Mexico has started proceedings against four officials accused of aiding the escape of drug lord Joaquin "El Chapo" Guzman from a maximum security prison. The federal judicial council said in a statement yesterday that two of those charged are members of the Mexican intelligence service who worked at the prison and two were prison employees in the control room. Guzman escaped through a tunnel dug to his cell on July 11. The four are accused of helping a prisoner escape and not following protocol in sounding the alarm. They're being held in the same prison where they previously worked. Proceedings have already begun against three others, including the person in charge of the control room and two guards. Guzman had escaped from another prison in 2001.
