National Security Commissioner Monte Alejandro Rubido showed a grainy video of a dressed Guzman pacing the room, looking behind the partition wall by his shower, sitting on his bed, then crouching again behind the wall, where he finally disappeared from view at 8:52 p.m. local time.
"He changed his shoes, and went to the shower," Rubido said, explaining the footage. "You can't see what he's doing."
The partition wall blocked the camera's view of a roughly 50-cm (20 inch) by 50-cm entrance hole to the mile-long tunnel shown by Mexican television earlier on Tuesday. It was one of two blind spots for the security cameras in Guzman's cell.The escape of Guzman, Mexico's most notorious drug lord, is a major embarrassment for President Enrique Pena Nieto, and was the second time the drug kingpin had broken out of prison.
