Mexico’s top security official announced Thursday what many Mexicans had suspected: the Jalisco drug cartel had long controlled the infamous “Puente Grande” federal prison where convicted drug lord Joaquin “El Chapo” Guzmán staged his first escape in 2001. The prison had become known for such lax standards that it earned the nickname “Puerta Grande,” or “Big Door.” Public Safety Secretary Alfonso Durazo said “it was a myth that it was a high-security prison.”
