The FBI began its investigation of Miguel Moran Diaz, who went by the name Aziz al Hariri, after the Miami man had posted ISIS propaganda on his Facebook page. An FBI informant then met with Diaz, who explained that he was a convicted felon and could not legally obtain a firearm. However, Diaz showed the informant he did have firearms nevertheless and even went shooting with the informant. During the sting, Diaz told the informant he was a lone wolf for ISIS, and he pulled up on his iPhone an edition of Al Qaeda's Inspire magazine, which he described as providing the instructions for the Boston Marathon bombers. Although the sting did not involve a terrorism plot, an ISIS-related counterterrorism investigation of Diaz was the genesis of the sting.
