The parents of a 15-year-old accused of murdering them and three of his siblings were religious extremists who isolated the family, according to court documents.
The accused teen killer, whose identity remains withheld due to a court order, was charged with the murders of his parents Mark and Sarah Humiston, 43 and 42, and siblings Katheryn, 7, Joshua, 9, and Benjamin, 13.
Police say he massacred his family at their $1.5million lakefront home in Fall City, Washington, on October 2024. Only his 11-year-old sister survived the attack after she played dead and ran away to a neighbor's home.
But the teen's lawyers said in court that his parents were abusive and tightly controlled their children's lives, isolating them from the outside world over their paranoia about the government and medical professionals.
The Humistons were extremely religious and particularly suspicious about the Covid-19 vaccine, according to court documents seen by KOMO News.
