I second dfchelbay's advice. with no heat and no electric, there should be no water either. no water in the pipes to expand when frozen and you should be fine.
This is incorrect. Even with city water, the house would have to be drained for there to be no water in the pipes. Well water, as many homes in CT are using, is no difference.
Water will still be sitting in the pipes unless it has been drained.
and thanks for the thoughts. The police won't get involved because it's a "civil" matter that needs to be taken up with the courts. This person, who we assume is her son, is referred to as a squatter and I have to go to court and legally take the house back. Now my father tells me on a daily basis to just go and change the locks (he's not even using a key, just leaves the front door unlocked - with his computer sitting in the living room to boot), but if I do that I risk being taken to court myself, so I'm trying to follow to rules, and the rules are breaking me down.


hope things end better than predicted!
She's really in a stuck situation. Thankfully, we seem to be past the hardest cold so if the pipes haven't frozen, they probably won't (barring a very cold snap).
