(AP) — A 21-year-old Omaha man has been convicted of killing a 16-year-old who had been wearing a red shirt, the color of a rival gang.

Online court records say Angelo Tolbert was found guilty on Wednesday of first-degree murder, assault and two weapons charges.

Police say the murder victim, Montrell Wiseman, didn’t belong to any gang. A 16-year-old girl also was hit by pellets from two shotgun blasts fired by Tolbert.

Investigators have said Tolbert and four others were driving around in a rival gang’s territory, seeking revenge for the September shooting death of a cousin of one of the men. They spotted Wiseman and two girls outside a house.
