The investigation began in March, when the FBI’s Joint Terrorism Task Force allegedly found communications between the Syrian-based terrorist group Katibat al Tawhid wal Jihad and the juvenile on Instagram. On August 6th, claim prosecutors, he changed his WhatsApp profile photo to an image of the ISIS banner. Krasner’s office says the juvenile received messages telling him how to build IEDs and that on August 7th, an FBI surveillance team observed him buying some of the items needed to build IEDs, along with tactical gear. The next day, U.S. Customs and Border Protection revealed to the FBI that more than a dozen international shipments of military and tactical gear had been sent to the juvenile’s home.

He called me right away. “You wanna find out what I’m really about?” he told me. “Text or call me one more time, and you’ll find out what I’m really about.”
