Story summary

Jonathan Hunter Kramer, a 21-year-old from Valencia, Pennsylvania, was arrested by the FBI on charges related to plotting an ISIS-inspired attack and receiving firearms and ammunition in support of terrorism. On September 12, agents seized a semiautomatic rifle, five magazines, and 190 rounds of ammunition when they tracked Kramer to a hotel. Federal prosecutors claim Kramer pledged allegiance to ISIS, offered to distribute explosive manuals online, and stated he was preparing for his "mission" but still needed a weapon. The FBI had monitored him since 2023, when as a minor, he was charged with plotting a mass-casualty attack and possessing child sexual abuse material. An anonymous tip in March prompted the renewed investigation that led to Kramer's arrest.
