Not only did he tunnel out, ‘El Chapo’ Ally Tunneled Out Months Before
Nearly 14 months before crime boss Joaquín “El Chapo” Guzmán escaped from his maximum-security cell through a tunnel, one of his Sinaloa Cartel lieutenants broke out of another prison in the same way. (emphasis added)
The passage through which Adelmo Niebla González and two underlings busted out of a prison in Culiacán, capital of Sinaloa state, in May 2014 shared many of the same technological and building styles.

We’re talking about a cartel known for its elaborate tunnels under the U.S.-Mexico border, but Mexican authorities put them all on ground-floor because,
“No one can say it was obvious this would have happened,” Mr. Rubido, whose more than three decades included several stints as Mexico’s top spy chief, said of Mr. Guzmán’s escape.
How do you spell c-o-r-r-u-p-t-i-o-n . . .
Hey, how about an open border!

At Breakfast to Talk El Chapo, Drug War Veterans Serve Up Cynicism
Over eggs at a San Antonio café, a reporter listens as former law enforcement officials and one ex-drug cartel operative swap theories about El Chapo’s latest escape and what it says about the U.S. and Mexico
Sinaloa became the McDonald’s of the drug trade. Customers could find its products — cocaine, heroin, and methamphetamines — everywhere. Operations ran so smoothly that after Chapo’s arrest in February 2014, many experts predicted that they’d continue to hum along without him. However, hopes ran high in the United States and Mexico that Chapo’s arrest would herald a new era of trust between the two governments. The arrest was seen as a sign that Mexican President Enrique Pena Nieto was serious about ending a long history of government corruption, and that Washington, after some skepticism, could trust him.
Chapo’s latest spectacular escape seems to have put an end to any such illusions.
