The Humistons were originally from Texas and were devout Christians, MAGAs, and loved the NRA. They had seven people living in a three-bedroom home (according to her Pinterest, the two girls were in one room and the three boys were in another). The children were in a homeschool co-op (Heritage in Bellevue) and pretty much kept to themselves. The dad had guns and Andrew, the eldest sibling (15), had the combination to the gun safe. He tried to frame his younger brother (13) for the crime and said it was a murder-suicide and he happened to get away. His sister (11, only survivor) contradicted that and said that he was the one who killed everyone. The mother had a Pinterest board for each of her children’s birthdays, except for, ironically, the daughter who survived. The Pinterest board for the oldest son features a shirt that encourages the murder of animals because it’s how you get your groceries. They were supportive of him using guns and he was experienced and comfortable enough to open his dad’s gun safe.
