Would you bail out your brother from jail?

10 years ago my grandmother died. My brother was executor to her trust. He stole money designated to me and my children to the tune of 15 grand. I didn't find out about it until 5 years after it happened when a friend of his confessed to helping him with the theft. Of course he denied it. We stopped talking to each other. I didn't pursue the money because I knew it was long gone. Yesterday I got a call from jail...he has been arrested, no one else to turn to-not his wife, daughter, or mother. He wants me to post his bail. It's set at 100,000.00. He has a lot of nerve.
