So is barb dead? Nobody has seen her or heard from her for months from what I can tell. Who thinks she kicked the bucket, Chris found out and tried to hurt himself and that's why they moved him, because he would be considered not fit to stand trial at the moment. I feel like it's plausible
Well I guess it is entirely possible that she has actually died and we just don't know about it (very unlikely), but that's just all speculation at this point since we have really nothing solid to go off, nothing in the legal process has really hinted at where she currently is either.
The field agents (more or less weens as people would put it when you look at what they do) haven't really been able to get any sort of concrete proof about the current situation of the house, only very small parts that don't give us a strong lead, since they're apparently too afraid to knock on the door (except for one but that was about a week after the motherfucking saga) or film anything around the house or windows to get an insight in what it looks like, they treat it like it's a fucking tourist destination, taking a bunch of selfies and posting it on the internet for reddit karma. What we can gather is that Barb probably isn't there right now, but who knows if she plans to return, potentially sell the house or the bank swipes it out from under her since she could not be paying it off anymore.
The common consensus around here is that Barb's sister Harriet may have gone to the house at some point to take care of her, but then the house has had some things removed or thrown out and it appears as if no one's home anymore, so who knows if Barb is with her sister currently or if she is in some type of care facility.
If you want to know about someone's date of death, a member of the family can contact the Virginia Department of Health for an official certificate if they want to know, or even the Green County can be pestered if you inquire (If you're not a member of the immediate family you might have to pay a fee, but you could still find out that way).
Otherwise we would just have to wait for some Probate to take place, but that normally isn't public once a person dies and we'd need to keep track of the estate when the time comes, some forum user probably will the moment that happens but it could potentially take years to go through.
