El Chapo’s Tunnel Escape Mystery

About one kilometer away, a small plot of land was quietly purchased.

Construction began slow, ordinary, unremarkable. Beneath it,

a tunnel was being dug. Seven meters down, then horizontally for nearly a full

kilometer. The tunnel would eventually include lighting, ventilation,

and rails. A motorcycle mounted on tracks. The engineering was impressive.

But this raises the most important question in the story: How did they know

where to dig? El Chapo’s cell sat above just seven centimeters of concrete. But aligning a tunnel

vertically to reach a specific point behind a privacy wall requires precision.
