IN KNOXVILLE, A HERO: Teen dies shielding trio from gunfire. “Fulton High School sophomore Zaevion Dobson’s death while shielding three girls from random gunfire during a gang shooting was just the kind of selfless act Principal Rob Speas expected from his student. . . . Knoxville Police Chief David Rausch choked back tears Friday at a news conference when he described how Dobson, 15, acted as a human shield to save three girls from a fusillade of bullets fired by three men. About a dozen people were in the area when the shooting began about 10:12 p.m. Thursday.” It was a gang shooting, apparently.
