MOUNT VERNON, N.Y. (PIX11) — Police arrested a 15-year-old in connection to a double stabbing in Mount Vernon that killed a girl and injured another Friday afternoon, according to officials.

The teen was charged with first-degree manslaughter, first-degree attempted assault and second-degree attempted assault.

Around 3:55 p.m., responding officers arrived in the vicinity of East Prospect and Gramatan avenues and found two girls, one with non-life-threatening lacerations and another with a critical stab wound, police said. The latter died while being transported to a hospital.

“I am devastated and completely outraged,” Mount Vernon Mayor Shawyn Patterson-Howard said. “We began celebrating the greatness and success of our youth and we ended it with a young life that has been taken by a senseless and inexcusable violence.”

The suspect was arrested late Friday night after police reviewed numerous recovered videos.

The girl who survived the attack is expected to make a full recovery.
