My golden child brother stole our late mother’s jewelry box before probate, not knowing I had already swapped everything for fakes.

My brother was always our mother's golden child. When she was diagnosed with terminal cancer last year, he showed up maybe twice at the hospital, while I spent seven months taking unpaid leave to manage her hospice care and change her bed sheets. A month before she passed she pulled me aside, handed me the key to her safety deposit box, and told me she knew my brother would try to raid it before probate. She explicitly told me to protect myself. I went to the bank that same week, took the real heirloom jewelry and vintage gold coins, and replaced them with cheap costume replicas from an estate sale. he broke into her apartment the night she passed away, stole the key from her desk, and cleaned out the bank box before the funeral was even over. He didn't say a word to me and pretended the box was empty all along. Two days ago, I found out he tried to pawn the collection to a private appraiser for sixty thousand dollars to cover his sports betting debts. The dealer immediately called the police for attempting to sell counterfit goods and now he is facing fraud charges. He called me sobbing asking for bail money. I let it go straight to voicemail. Just needed to get this off my chest.
