Another sibling revealed their adoptive father pinned the daughter against the fridge while Marlaina beat her up.
Police also found dog leashes tied to door handles to keep children in their rooms.
The girl told police she and her siblings were denied food and water, even when they used the bathroom.
She said she "has personally observed her siblings drink water from the toilet because they are thirsty", according to local new outlet ElkoDaily.
The children also told police they were repeatedly beaten by Marlaina and that they were smacked with Jonathan's studded buckle belt.
Both parents were charged with child abuse and booked at the Elko County Jail on $100,000 bond.
