A 15-year-old boy accused of murdering his parents and three siblings east of Seattle this week tried to blame his brother for the deaths, but he pretended to be dead and his surviving sister arrived at a neighbor’s house. He ran away and told the police the truth. In court documents released Thursday, authorities said they carried out the shooting.
The boy was charged Thursday in juvenile court with five counts of aggravated murder. Washington state law requires a hearing before the case can be transferred to adult court.
The 11-year-old sister who survived Monday’s shooting told investigators that the defendant had recently been in trouble for failing a test at school and that the gun he used belonged to her father. She said he was the only one of the children who knew the code to the lockbox where their father kept it.
The King County Coroner’s Office said the victims were Sarah Humiston, 42, Mark Humiston, 43, and their children, Katherine Humiston, 7, Joshua Humiston, 9, and Benjamin. -Identified as Mr. Humiston (13 years old).
According to a probable cause affidavit by King County Sheriff’s Detective Aaron Thompson, the defendant reported around 5 a.m. Monday that his 13-year-old brother had shot and killed his family at their Fall City home. I’m having trouble watching porn.

When officers arrived, they detained the 15-year-old boy in the driveway and discovered his body inside. The 11-year-old boy was treated at a Seattle hospital and later released, a hospital spokesperson said.

The boy is scheduled to appear in court Friday afternoon.
