McWhorter, 29, and Morris, 23, of Clarence, said that when they arrived at the Dar al-Farooq Islamic Center in Bloomington on Aug. 5, 2017, they broke a window and threw a lit pipe bomb and a gasoline mixture inside, causing an explosion, fire and extensive damage. No one was injured in the attack, which happened just as morning prayers were about to begin, shaking members of the local Muslim community.
