A 15-year-old boy was arrested on Thursday and accused of fatally shooting five of his family members, staging the scene at their Fall City, Washington, home to frame his 13-year-old brother, the King County Prosecuting Attorney’s Office announced. The 15-year-old, whom HuffPost is not naming, is charged in juvenile court with five counts of aggravated murder in the deaths of his family members, identified by the medical examiner’s office as siblings Katheryn Humiston, 7; Joshua Humiston, 9; Benjamin Humiston, 13, and parents Sarah Humiston, 42, and Mark Humiston, 43. The 15-year-old was also charged with the attempted murder of his 11-year-old sister, who survived the mass shooting by playing dead, according to a probable cause document obtained by HuffPost.
With tears in her eyes, the 11-year-old told detectives she was in the bedroom she shared with Katheryn when they were both woken up to the sound of gunshots, according to the document. She went to go check what was happening, then saw Joshua and her dad laying bloodied on the hallway floor. Katheryn got out of her bed and entered the hallway, but was fatally shot, according to the probable cause document.
The 15-year-old then entered the bedroom holding their father’s silver Glock, the document said. The 11-year-old told detectives her brother shot at her once or twice, with a single bullet hitting her hand and neck, according to the document. She said she immediately felt pain.
