Report released on Marysville-Pilchuck shooting; gunman's motive still unclear

SEATTLE -- Newly released investigative records show the high school freshman who fatally shot four friends then himself planned the slayings and sent a text message to family members moments before opening fire.

The final, 1,400-page report made public Tuesday by Snohomish County authorities says Jaylen Fryberg's motive remains unclear for the Oct. 24 shooting at Marysville-Pilchuck High School cafeteria.

On Fryberg's cellphone, investigators found a series of messages the 15-year-old sent in the minutes before the shooting began. He sent a photo of a pistol between his legs to one friend, and sent a prepared group text to his family saying he intended to take his friends with him to "the other side."

Two minutes after that, the first 911 call came in about killings at the school about 30 miles north of Seattle.

“Today is not an easy day for the Marysville-Tulalip community. The public release of the SMART investigation into the events of Oct. 24, 2014, is incredibly emotional for anyone who was affected by this tragedy. None of us will ever forget the feelings of grief and loss we experienced that day," said Marysville Mayor Jon Nehring in a statement. "As a community, we have grown and become stronger since Oct. 24.  We have strengthened existing partnerships and forged new connections – not only in our community but throughout the region. As we move forward, we are focused as a community on our continued support for each other.”
