I've not updated the blog; we recently returned from a 10-day trip to north Idaho. Sis-in-law is now in the community "Restorium" (yes, they actually call it that) and is living in much better conditions. The hoard is under lock and key so she will not worry. We're keeping our fingers crossed it will stay that way.
We did learn one apparent fact: it is much easier to remove the hoarder from the hoard, than to take the hoard from the hoarder.
