How Mexico’s Most-Wanted Drug Lord Escaped From Prison (Again)

First, Mr. Guzmán is believed to have climbed down through a two-by-two foot hole underneath the shower in his cell in the prison’s most secure wing.

The shower opening led to an elaborate tunnel almost a mile long. The tunnel was equipped with lighting, ventilation and a motorcycle on rails that was probably used to transport digging material and cart the dirt out.

It led to a construction site with a bare-bones compound in the nearby neighborhood of Santa Juanita.

Through a hole in the ground, a ladder led to the middle of the construction site.

Construction on the compound was started some time after February last year, satellite images show. Mexican authorities began a sweeping manhunt, shutting down an airport and holding 30 prison employees, including the head of the prison, for questioning.
