UPDATE: I have proof my landlord stole and hid my keys. What now?

Today, Susan asked me to have a chat with her on the porch. I started recording.

First, she apologized for her behavior, saying she was without her “heart medicine” for 8 days and that’s why she was acting crazy. But then she went right back into being rude.

She told me changing the locks was illegal. A cop literally told me to. I said “well now you’ll have nice new locks and I’ll give you the keys when I leave” She said she doesn’t trust me, and she needs the original key back. So I said “I can’t, my keys went missing.”

And then she admitted to taking them and “throwing them on the porch by the fishtank” (the fish tank was gone before my keys went missing)

Later she showed me that they were in a bush in front of the porch the whole time, and I recorded this too. But here’s the problem, I asked her when she took them and she thinks she took them out of my hands. This never happened. She also thinks she took them because she was mad I changed the locks, which obviously wasn’t the case. I changed the locks because my keys were missing.

What can I do here legally??

I have video of her admitting to taking them and hiding them and also video of her digging them out of the bush. But she’s insane and doesn’t have good memory, it’s her word against mine about *when* she stole them. I’m 100% sure she came in at night and took them, she claims she took them out of my hands.
