Found guns that were "stolen" from my parent. [WA] : legaladvice

I'll try to keep this short.

Back in 2012 my dad hired someone from a "half way house" like program. This woman was a felon.

Her housing arrangements fell through, and my dad offered her a place to stay. Nothing inappropriate. She was in my parents guest home.

My dad started having some medical issues around that time, and was prescribed medication.

At one point he was taken to the hospital, for his final week, and during that time the woman entered the main house, and stole a suit case full of goods, all captured on the security system in very high detail.

One of the things she stole was my dads bug out bag, which had 3 pistols, I'm not a gun person and am not sure what they were aside from one revolver and two semi automatic pistols, ammo for the guns, survival supplies, and about $50K in cash. (My dad did not trust the banks, and kept large amounts of cash all over his house, business, etc.) He did however keep a somewhat up to date ledger saying what was in each hiding spot.

The ledger, security footage, and footage of the woman selling a bunch of the survival supplies was enough to get her convicted of several crimes, and she is still in jail today, and I believe she won't be scheduled for release for at least another decade, or so.

She of course plead not guilty on most counts, however was convicted on most.

The issue is, one of the key parts of her trial was based on her taking, having, and not releasing the location of, the pistols. She says she did take the duffle, and some other stuff, but all that was in it was survival equipment, and the including knives, but no guns, and no cash. I did not attend the trials, and do not have exact details, but nobody believed her.

I now live in my parents house, as my dad passed when all this was starting, and my mom moved out of country.

I found a ledger from my dad that indicated he secured all fire arms, medications, and cash stores when the woman moved in. The ledger indiciates survival gear was still in the bug out bag, but the guns were moved from it, and other locations, in to safes that were distributed throughout the house and land.

I found the one that supposedly had the guns from the bug otu bags, serial numbers match, in a floor safe in the unfinished basement, hidden under dirt, and it had the 3 guns, the $50,000, and a few other items.

This woman was put away for a crime she did not do. She stole from us, but less than $1,000 in supplies, not fire arms and large sums of cash.

One other kink in the system, I am also a felon and am not allowed to have these 3 guns, which are still in the floor safe, or any of the other fire arms which I assume are accurately logged around the land.

Any advise would be greatly appreciated.
