Guzmán, better known as “El Chapo,” escaped on Saturday when he slipped through a 20-inch square opening in his cell and then proceeded to climb approximately 30 feet down to reach the mile-long tunnel, according to The Los Angeles Times.
The intricate tunnel was even tall enough for the multi-billionaire to stand in and came with ventilation and lights. This escape tactic even had motorized rails to help workers move dirt through while they were building it.
Guzmán then reached a house that was under construction located right outside the prison. Clothes were allegedly placed there for him to change into.
The tunnel likely cost around $5 million and took about a year to build, says former chief of international operations for the Drug Enforcement Agency (DEA), Michael S. Vigil.
