Joaquin "El Chapo" Guzman was considered the world's most powerful drug lord until his arrest in Mexico in February 2014. He escaped from a maximum-security prison on July 11, 2015.

This screen grab of security video, dated July 11 and released by Mexico's National Security Commission, shows Guzman inside his cell at the Altiplano prison in Almoloya de Juarez, Mexico. He is looking at the shower floor shortly before escaping through a tunnel below, authorities said.

A journalist climbs a ladder to get out of the tunnel that authorities say Guzman used to escape.

Journalists exit the tunnel on Tuesday, July 14.

Yellow police tape surrounds the construction site where the exit of the tunnel is located.

Federal police guard a drainage pipe outside of the prison on Sunday, July 12.
