Inmates work on the construction of the bell tower of a prison chapel inside the state prison in Ciudad Juarez, Sunday, Jan. 17, 2016. On Feb. 17, Pope Francis will visit this prison and meet with inmates. Some see Pope Francis’ visit to Ciudad Juarez as the capstone in the city’s transformation from one of the most violent places on earth; others hope the Pope will draw attention to the problems that remain in the bustling border metropolis.
