FALL CITY, Wash. — A teen was taken into custody after five people were killed at a home in Fall City early Monday morning, according to the King County Sheriff's Office (KCSO).
Deputies found two adults and three juveniles dead in the home. A spokesperson said a "high school-aged" teen will be booked into the King County Juvenile Detention and will face first- or second-degree murder charges, the spokesperson said.
Another teen, believed to be related to the suspect, received medical aid from a neighbor and was taken to Harborview Medical Center for treatment. She is in satisfactory condition.
The Snoqualmie Valley School District confirmed that at least two of the victims are "school-age." The victims did not attend Snoqualmie Valley schools. However, "we recognize that events like this can affect all of us, including our students," the district wrote. Counselors and support staff will be available all week to assist students.
A neighbor said a couple and their five children live in the home that is now a crime scene.
"I'm just in total shock," neighbor Lynne Trowern said. "I keep bursting into tears. That is why I have to go to my daughter's house because I can't be here on my own. I just keep seeing the faces of the children."
At around 4:55 a.m., multiple people called 911 reporting a shooting in the Lake Alice neighborhood. KCSO deputy Mike Mellis said when deputies arrived they found a "tragic scene" and they are investigating multiple homicides. Major Crimes Unit detectives are responding.
"I can say that it's going to be really a tragic event for the community, for anybody who has any connection out here," Mellis said.
Mellis said this is potentially a domestic violence incident. There is no ongoing threat to the community and the scene appears to be a "self-contained situation."
Mellis said the initial response to the investigation was "massive" and they are calling in more resources, including support for both first responders and community members.
He expects that processing the scene will take multiple days. The Washington State Patrol's Crime Scene Response unit has been called out to do the bulk of that work.
"That implies that this is a significant scene that is going to take a lot of expertise, a lot of time," Mellis said.
Details about exactly what happened are sparse, but Sheriff Patricia Cole-Tindall said when she learned about the incident earlier this morning she was "very sad, very disturbed."
The King County Medical Examiner will release the identities and ages of the victims.
