Girl injured in attack that left five people discharged from hospital near Fall City

SEATTLE — An 11-year-old girl who was injured in an attack that killed five other people was released from Harborview Medical Center Tuesday evening, according to a hospital spokesman.

Her parents, Sarah and Mark Humiston, were identified at a vigil Tuesday by one of their children’s youth soccer coaches. According to police, a 15-year-old who appears to be a member of the family killed her and three of her children in their Lake Alice home.

Property records show the Humistons purchased the home in 2019.

According to a statement from the company, Mark Humiston worked as an electrical engineer at Hargis Engineers.

“We are surprised and saddened by the tragic events that have resulted in the loss of a respected colleague, mentor and friend, as well as the loss of immediate family members,” the statement said. “Mark’s leadership and vision were an integral part of our company and we will miss him greatly. Our thoughts are with his surviving family, friends and colleagues at this difficult time.”

The judge also ordered the suspect to have no contact with his immediate family, citing the initials of a surviving family member.

The Seattle Times typically does not name suspects until they have been charged and does not name juvenile respondents unless they are charged as adults.

King County Sheriff’s Deputy Mike Mellis described a “chaotic scene” at the home Monday and said there were firearms involved, but the cause of death of family members was not released by the King County coroner’s office.

Mellis did not provide any information about the children’s ages or genders. He declined to comment on whether the incident involved parents and their children, but said the suspect and victims appeared to be family members.

Prosecutors expect to make a charging decision by Thursday. The boy has no criminal record.

King County Councilwoman Sarah Perry, whose district includes Fall City, said in a statement Tuesday that five of seven family members were killed.

“At this time, I ask you to join me in praying for peace and healing in your hearts for all family members, the community members of Lake Alice and Fall City, and others affected by this terrible situation,” she said in the Press release statement.
