Just months later, the same Frisco high school reeled yet again when a 17-year-old junior was stabbed by another student at a school track meet on Wednesday,

Frisco police released the arrest report in the deadly high school track meet stabbing that left 17-year-old Austin Metcalf dead. The alleged suspect, 17-year-old Karmelo Anthony, appeared in court Thursday. NBC 5’s Maria Guerrero takes a closer look at the case and the grief in Collin County.
