Officials in Mexico are offering a reward of nearly $1 million for the capture of 30 inmates who broke out of a prison in the northern state of Nuevo Leon on Sunday.

The governor says the inmates staged a riot, during which 44 people died, to create a diversion for their escape.

It was a jail break that epitomized the Mexican drug war: Rival gang members brutally killed each other, corrupt public officials looked the other way, and dangerous criminals went free.
