Details about the 14-year-old who opened fire in the school cafeteria of Marysville-Pilchuck High School in Washington on Friday are beginning to emerge. Jaylen Fryberg was a freshman football player who was crowned homecoming prince just last week. Just before shooting himself, Fryberg shot three girls and two male cousins of his, 14-year-old Nate Hatch and 15-year-old Andrew Fryberg. One of the girls was killed; her identity has not been released. “My grandson and the shooter were best friends,” Hatch’s grandfather told ABC News. “They grew up together and did everything together.” Andrew Fryberg underwent surgery for a head wound and is listed in critical condition. Hatch is in serious condition; both boys have been transferred to another hospital. The two wounded female victims remain in critical condition. Officials met with relatives to ask about birthmarks and descriptions of their children’s clothing to help identify them, since the girls' head injuries were so severe they were not immediately identifiable. According to student witnesses, Fryberg pulled out the gun in the cafeteria and began shooting in a calm, methodical way with “no arguing, no yelling.” The gun Fryberg used was legally acquired, though it is unclear by whom.
