A 17-year-old boy who opened fire in his Nashville high school's cafeteria fired a total of 10 shots from a 9 mm pistol within 17 seconds of entering the room.

A teenager opened fire at Antioch High School Wednesday killing a student and leaving a mourning community that has already seen two mass shooting incidents in recent years.

One 16-year-old girl named Josselin Corea Escalante was killed, and two other students were injured. The injured students were taken to Vanderbilt Pediatrics for medical attention. The shooter shot himself and died from the self-inflicted wound.
