On Tuesday, authorities offered new details from a search of the Hart’s home in Washington state.

Investigators said it didn’t appear that any children lived there. There weren’t a lot of kids’ clothes or toys and the rooms aren’t personalized.

“Where did the kids live, what part of the house did they live in, what sort of regimen or what was going on behind the house. Those types of questions came up because it wasn’t what you would term a house that had kids in it or it didn’t appear that way,” said Clark County Sherrif’s Department Sgt. Brent Waddell.

Investigators removed a laptop and an iPad from the house. The iPad was handed over to the FBI.
