Joaquin 'El Chapo' Guzman was found guilty on Tuesday of 10 charges relating to masterminding an international drug smuggling conspiracy.
He'll be sentenced in June, though it's believed he faces life behind bars.
And it's understood the 61-year-old cartel kingpin will be sent to ADX Florence, Colorado, a brutal prison from which no one has ever escaped.
El Chapo will be locked up with bombers, hate-preachers and domestic terrorists at the 490-bed slammer, known as the "Alcatraz of the Rockies".
Photos taken in the tiny cells in Colorado show the squalid conditions El Chapo faces.
