Dallas (AP) – A grand jury has indicted a suburban Dallas teenager who authorities say was planning a mass shooting at a mall, taking his inspiration from the Islamic State terror group. Seventeen-year-old Matin Azizi-Yarand was indicted Thursday on charges of making a terroristic threat and also solicitation to commit capital murder of a peace officer. He’s been held at the Collin County jail since his arrest in May at a high school in Plano.
