KNOXVILLE, Tenn. (WATE) – The three shooters convicted in the death of teen hero Zaevion Dobson were denied a new trial on Friday.

Fifteen-year-old Dobson was killed in December 2015 while protecting two of his friends from gunfire.

Dobson became the face of the local anti-gang movement, sparking a citywide conversation and a call to stop the violence.

Christopher Bassett, Richard Williams III and Kipling Colbert Jr. were eventually charged in his murder. Bassett was convicted of first-degree murder. Williams and Colbert are convicted of facilitation of first-degree murder.

The judge denied the new trial but said their case can proceed to the appeals court if they so choose.
