A legal expert says that a self-defense strategy might be an uphill climb for a Texas teen charged with murder after allegedly stabbing another teenager to death during a high school track meet.
Karmelo Anthony, 17, is accused of stabbing 17-year-old Austin Metcalf to death April 2. NBC News reported that the incident unfolded when Anthony, a Centennial High School student, was sitting under the Memorial High School track team's tent. Metcalf, a member of the Memorial High School track team, told Anthony to move.
