KNOXVILLE, Tenn. (AP) — Jurors found one defendant guilty Thursday of first-degree murder and two others guilty on a lesser charge of facilitation of first-degree murder in the 2015 death of a Tennessee teen who was lauded for courageously shielding his friends from gunfire. Christopher Drone Bassett, 22, was found guilty of first-degree murder in the death of 15-year-old Zaevion Dobson, a promising high school football player whose act of bravery drew praise from then-President Barack Obama. Kipling Deshawn Colbert, 22, and Richard Gregory Williams III, 23, also had been facing first-degree murder charges but were instead found guilty of facilitating the murder.
