"El Chapo" used airplanes, submarines and trains to smuggle drugs into the U.S.

The fugitive Mexican drug lord Joaquín "El Chapo" Guzmán used airplanes, submarines, trains, boats and long tunnels under the border to smuggle tons of drugs into the U.S., according to U.S. court documents.

The head of the Sinaloa cartel is an old friend of the U.S. authorities, which have offered a US$5 million reward for information leading to his capture.

"Joaquín Guzmán managed to transport cocaine from Colombia to Mexico, from Mexico to the border, and then into and throughout the United States, using various means, including planes, trains and trucks," reads the indictment filed in a federal court in the Southern District of California.

Court documents also report the use of submarines, sailboats and long tunnels to smuggle drugs.

In this court, located in San Diego, California, the capo is facing several counts of drug trafficking, money laundering and criminal organization along with his son Iván Archivaldo Guzmán Salazar, alias "El Chapito" and another Sinaloa cartel leader Ismael "El Mayo" Zambada.

On July 11, "El Chapo" stood up from his bed, walked to the far corner of his prison cell in the State of Mexico, and escaped through a sophisticated and custom-engineered tunnel system.
