Internal documents of the Drug Enforcement Administration obtained by The Associated Press reveal that drug agents first got information on escape plans in March 2014. That was about a month after Guzmán was captured in Mazatlán, Mexico.
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.
Paulo Flores, Ronald Roland and Manoel Gonsalez allegedly obtained the drugs from members of Colombia's FARC and took them to Mexico for the Sinaloa Cartel and Los Zetas on planes departing from Venezuela that passed through Honduras.
Xilin Chen and his son, Tom Chen, laundered money for Mexican drug cartels.
