PHILADELPHIA — In a record year for gun violence at high school sporting events, Da’Vion Harper played a football game Wednesday with a somber tribute written on the shirt beneath his jersey: “R.I.P. Micah.” Beneath his helmet, Harper drew the number 10 on one cheek and a cross on the other.
On Friday night, 10-year-old Micah Tennant attended a playoff game in southern New Jersey between Pleasantville High School and Camden High School. The game was interrupted in the third quarter by what the authorities are investigating as a retaliatory shooting.
