Newly released video from an officer’s body camera and a surveillance camera at a Texas running track captures the moments after a teenage athlete fatally stabbed another teen from a rival team in the stadium bleachers during a high school meet last year. Karmelo Anthony was convicted of murder on June 10 in the death of Austin Metcalf and sentenced to 35 years in prison. The surveillance video shows Anthony running down the bleachers and away from the tent before stopping and walking back. The officer's bodycam video shows Anthony being placed in handcuffs and obeying all commands. He then began crying, saying “he put his hands on me.”
