The 15-year-old boy accused of gunning down his parents and three of his siblings at their ritzy Washington State home has been banned from contacting his sister, who was the sole survivor of the shocking massacre.
The suspect – who has not been named publicly due to his age – was handed to the no contact order during his first court proceedings on Tuesday, the King County Prosecuting Attorney’s Office said.
The prosecution asked the court to charge the teen five counts of first-degree murder and one count of attempted first degree murder.
The surviving sister, 11, was shot twice during the disturbing killing spree.
She was taken to Harborview Medical Center in Seattle after receiving medical aid from a neighbor.
The children’s parents were identified late Tuesday as Mark Humiston, 42, and his wife, Sarah.
Humiston was a software engineer at Hargis Engineers in Seattle, according to his LinkedIn.
The three slain kids are all believed to have been teenagers, with the 15-year-old being the eldest.
