My mother died and a week later her landlord is letting people into the house without notifying anyone. [Virginia]

My mother died unexpectedly last Tuesday. It has been as terrible as you can imagine. This Tuesday, my wife stopped by my mother's house to make sure everything was okay. My mother had some sketchy friends.

As she gets there, she finds a woman inside getting some DVDs. Now, we had locked all the doors so this was odd. On top of that, all the jewelry was stolen from my mother's bedroom and it was obvious people had gone through the drawers, probably looking for leftover pills. My wife called the police and the landlord said he gave the woman permission to enter the house. According to him, when they arrived, the air conditioning window unit had been knocked in the house and the jewelry was stolen. Nevermind that he never called any of us about this. He is a longtime acquaintance of my uncle's and has their numbers, so no excuse.

Now at first you might think the woman getting her DVDs might have stolen them and made it look like a robbery. I doubt it personally because I know they actually were her DVDs and I really think she was legitimately just stupid or callous enough to get them without asking me. But whoever did it must have known my mother personally. Her home, a trailer, is considerably off the road and in a fairly decent neighborhood. No thefts have been reported there at least in the six years my mother has lived there. Then my mother dies and within a week people are breaking into her home. Not a coincidence.

So, the police can't do anything about the jewelry unless I give them specific descriptions of each piece, which I can't. Honestly, it was all cheap anyway but I still want whoever did this to face charges. I stopped by the nearest pawn shop and asked if anyone brought in a bunch of cheap jewelry. Sure enough someone had stopped in the day before with a bag of jewelry but it was all worthless to the pawn shop, so he didn't have their information.

Anyway, I got sidetracked there but I felt it's necessary to give all the information. Basically, the landlord was letting people in the house, at least one, and now my mother's stuff is stolen. What can I do and would it even be worth my time?

Thank you.

EDIT: I'm not saying someone he let in stole the stuff, just that it happened on top of everything else. But aren't there some laws in place that prohibit a landlord letting people into someone else's home?
