On Monday, 17 year-old Santos Colon of Lindenwold, New Jersey pleaded guilty to charges related to a plot to kill the Pope.
The teen had reportedly devised a plot to kill Pope Francis and detonate explosives during the Holy Father's visit to Philadelphia for the World Meeting of Families in 2015.
The event was the last stop on Pope Francis' six-day trip to the United States, during which he also visited New York City and Washington, D.C.
Hundreds of thousands of people were gathered at the Benjamin Franklin Parkway for the final papal Mass on Sunday, September 27th, 2015.
