Santos Colon Jr. collaborated with an FBI informant and undercover agent in a supposed ISIS plot to shoot Pope Francis and set off an explosive device during the papal mass in Philadelphia in 2016. The undercover agent portrayed himself to Colon as a sniper, and Colon and the informant engaged in target reconnaissance as part of the plot. Colon also asked the informant to purchase bomb materials. Colon was a minor when arrested, but at age 17, he pleaded guilty as an adult.
