3. Guzman faces several indictments in Mexico and the United States. Officials in the U.S., where Guzman is on the Drug Enforcement Administration's most-wanted list, planned to file for extradition earlier this year. Former Mexican Attorney General Jesus Murillo Karam, however, said in January that Mexico planned to keep and prosecute Guzman, according to the AP.

4. Earlier this year, Murillo Karam said Guzman could not break out of prison again. Despite Guzman's history of paying off authorities and other residents to get his way, Murillo Karam in January shrugged off concerns over whether the drug lord could break free, saying the risk of a second escape "does not exist." 

5. Other well-known drug traffickers are housed at Altiplano. They include Miguel Angel Trevino, leader of the Zetas drug cartel, and Edgar "La Barbie" Valdes Villarreal of the Beltran Leyva cartel, the AP reports.
