Teen faces 5 potential first-degree murder charges for Fall City mass shooting

The 15-year-old boy who allegedly shot and killed five family members at a home near Fall City early Monday morning waived his right to attend his first appearance Tuesday in King County Superior Court. One of his public defenders, Amy Parker, spoke on his behalf.

King County prosecutors requested that Judge Joe Campagna find probable cause for five counts of first-degree murder, and one count of first-degree attempted murder.

The teen has not been officially charged. Prosecutors are expected to file formal charges on Thursday, including whether they will seek to try the boy as an adult. An arraignment is scheduled for Friday.

Judge Campagna described the allegations as of the "gravest possible seriousness," and ordered the teen to remain in secure juvenile detention and to have no contact with his sole immediate family member who survived the attack, an 11-year-old girl, who was hospitalized.

Parker did not argue for her client's release, but stressed that the 15-year-old is a child with no criminal history who "enjoys mountain biking and fishing."

A spokesperson for the sheriff's office previously said that the home where the mass shooting took place was not a "problem house," and that officers had not been to the house for “any significant reason for years.”

After police responded to 911 calls for the incident early Monday morning, a sheriff's office spokesperson said, the 15-year-old was taken into custody without confrontation with deputies.

Two adults and three teenagers were found dead inside the house. A fourth child, the girl, suffered injuries and was rushed to Harborview Medical Center in Seattle.
