This story says California authorities are comparing notes with authorities in Texas, where they lived previously. It wouldn't be a surprise if there are some Texas charges, too.

There's an article floating around that I saw yesterday which has photographs of the interiors of two houses the family had occupied in Texas, taken by the eventual buyers. In one, the house is cleared of belongings but the walls and carpets are shown to be in a filthy and thoroughly disgusting state. In the other, the home is still filled with some hoarder-type clutter and there are several features that stood out to the buyer as particularly odd, such as inexplicably-damaged bedroom closet doors, and screwed wood panels installed over and blocking the air vents.
