A Wyoming teen was charged as an adult for first-degree murder after he opened fire on a group of teens killing one and injuring another. Tyler Burns, 19, suffered a gunshot wound to his stomach and begged for his life before 16-year-old Phillip Sam shot him in the head Oct. 5, in a public execution practically unheard of in the city of Cheyenne. Burns died at a hospital one day after the shooting where Sam opened fire on 13 teens. The teens began to scatter until just Burns, Sam and a minor who was with Sam were left alone.
