Here's a good reason for everyone to spend this weekend doing an inventory of your guns. Write down the make, model, serial numbers, condition, and identifying marks and customizations. Keep a copy for yourself and give another copy to your legal representation, trusted friend or family member, or in a safety deposit box. My good friend, Maggie, holds the copy of my inventory. My insurance agent holds the other copy (when I added up what I paid for them, I was shocked. Shocked enough to add them to my insurance!)
Sadly, someone set wheels in motion that will have sad repercussions for the whole family. Suspicion will eat at everyone from now on. I am so sorry for you and your family.
