Death invitation: Marysville Shooter Jaylen Fryberg Lured Victims to Lunch.

The Washington high-school freshman who shot five friends in the school cafeteria, killing two, invited them to the ambush by text message, police revealed on Monday. Jaylen Fryberg, 15, used a relative's legal .40 caliber Beretta pistol to gun down his pals and then shoot himself in Friday's attack at Marysville Pilchuck High School near Seattle. Fryberg did not leave behind a note and investigators are still combing through text messages to determine a motive. "I don't know if the why is going to be something we can provide," Snohomish County Sheriff Ty Trenary said.

But he said it was clear from the initial investigation that Fryberg targeted the victims. "We know that the shooter had arranged to meet with friends at the lunch table," he said. "It's our understanding he did so by texting."

One girl died, Zoe Galasso, was killed at the scene. Another, Gia Soriano, 14, died at the hospital on Sunday evening. Shaylee Chuckulnaskit, 14, was in critical condition at Providence Regional Medical Center while Andrew Fryberg, 15, was in critical condition and Nate Hatch, 14, was in satisfactory condition at Seattle’s Harborview Medical Center.
