Federal Social Readaptation Center No. 1

It is the 11th of July, 2015.

A prisoner in the high security Altiplano prison in Mexico takes a shower in his cell, going out of sight from the CCTV cameras that monitor him 24/7.

Minutes pass and he doesn't emerge.

Then when prison guards inspect his cell, they find that he has vanished through a trapdoor in the shower floor, along a mile-long tunnel complete with air conditioning and a motorbike.

Now, this time, there was no long tunnel and no extended gun battles.

After 13 years on the road, Joaquín Guzman, El Chapo, was taken into custody, and he was flown to a Mexican prison in Altiplano.

Now, his capture demonstrated what the investigation had finally achieved: technical access, patient analysis, pressure on the inner circle of the cartel, and a tactical unit that was able to move in quickly.

And now, El Chapo was in the country's most secure prison under constant observation and facing extradition demands from the United States.

But the same weaknesses that had shaped his career opened another rollout because on the evening of July 11th, 2015, surveillance video inside the prison showed Guzman walking into the shower area of his Altiplano cell.

Uh, it's a very small portion that's screened from the camera for privacy.

But he never returned.

Now, reports suggest that Guzman bribed or threatened the officer and, and actually warned those officers that they-- that other gunmen might be coming.
