The Bolivian government announced Thursday that its security forces are keeping a close watch on the country’s borders following the escape of Joaquin “El Chapo” Guzman Loera, a drug lord, from prison cell in Mexico.

In the grainy, black and white footage, El Chapo was seen staring into the space behind the shower partition, where now is known as the entrance to his escape tunnel was hidden.

The National Security Commission did not immediately respond to questions about the time.

Up until his departure, Guzman’s behavior had been “normal” for a person who spent many hours in a small cell, Rubido said.

“El Chapo” – “Shorty for his 5-foot, 6-inch stature – is partially obscured as he walks around his cell and shower area before finally walking across the cell, crouching and vanishing through the hatch late Saturday”.

The video released to the public Tuesday showed Guzman disappearing at 8:50 p.m. behind a half wall that blocked the camera’s view of his shower.

The former boss of the ruthless Sinaloa Cartel had previously escaped from a different maximum security prison in 2001, having reportedly been wheeled out in a laundry cart.

An official with the Attorney General’s Office said one hypothesis was that Guzman used the grating and tortilla pieces as a kind of calendar, but said another was that it was a game he created for himself. Notably, Guzman sported longer hair while, per prison regulations, all the other inmates observed had shaved or closely cropped hair reported the LA Times.
