Jaylen Fryberg, 15, allegedly sent a text message to his family giving his farewells, outlining his funeral wishes, and apologizing to the parents of the teenagers he was about to kill, before opening fire at Marysville-Pilchuck High School in Washington on last Oct. 24, investigative documents revealed, according to the Associated Press.
"I love you family. I really do. More than anything. I needed to do this tho...I wasn't happy," he said minutes before the incident. "And I need my crew with me too. I'm sorry. I love you."
Fryberg's motive still remains unclear, but the 2,200-plus pages of investigative documents released Tuesday, which partially consist of interviews with many students who were just a few feet away when Fryberg began shooting, may help investigators, according to Sky News.
According to one student, Fryberg, a Native American football player, was facing suspension from the football team over a fight which was sparked by a racist comment.
Another student, according to the the report, believes what "pushed Fryberg over the edge" was the fact that Fryberg's girlfriend had broken up with him one day before the shooting, reported The Seattle Times.
He called his friends to the cafeteria before opening fire, injuring and killing some of them before killing himself.
Zoe Galasso, 14, died at the scene. Gia Soriano and Shaylee Chuckulnaskit, both 14, and Andrew Fryberg, 15, later died at area hospitals. A 14-year-old survived a gunshot wound to his face. Two other 14-year-old females who were seated at the table were not injured.
The gun that Fryberg used in the shooting was illegal and belonged to his father, Raymond Fryberg. Raymond Fryberg is going to trial for the illegal firearm on Sept. 21.
