My understanding is that she was a type of Druid witch and the merging of the old magic and the new holy land made her incredibly powerful. She killed the men as a sacrifice to the gods.

that makes more sense. She has all the similarities of the Celtic woodland godess, who is also similar to the Roman goddess of the Moon and woodland(Diana)
But if shes some kind of goddess, how did she turn from human to goddess?? how does that make sense? gods are not descended from humanlife,lol.

I think the police officers said they knew their family abandoned them, but anything is possible.

Interesting read. I think you nailed.
Something about this makes me wonder if the feral pig children aren't Gaga's.
