Celda de "El Chapo"
Valentín Cárdenas Lerma permanece en el penal federal de El Rincón, en Nayarit, desde hace tres años, luego de la fuga del Joaquín Guzmán Loera
Valentín Cárdenas is one of the 20 people accused of helping the leader of the Sinaloa Cartel to escape from prison in July.
Along with Ramón Eduardo Pequeño, three other officials have been removed from office so far after the escape of Mexico's most-wanted drug lord.
More than 30 employees who were in the prison during the escape are being interrogated to determine if they are involved, among them Valentín Cárdenas Lerma, director of the prison; the deputy director, guards and the medical staff that supplied drugs to Guzmán.
