All very sad. Good for you sticking up for her.
However as long as she is in that environment she is at risk of further emotional and possibly physical abuse. The dynamic of the "who's in and who's out" of the JW community is a rather unique one and you are not going to get help from elders, PO's, bethel or anyone in there. Even elders in good standing, with political clout and otherwise have a hard time helping people like your mom. There is no way they are going to help the new Ray Franz (sorry if I am overstating things)
I new a man (the congregation PO with Bethel clout in his pocket) that was beating his wife and although some knew it was secretly hushed, and her son who went on to become an elder himself was a witness to it all just as you. He was hand tied as you were. In the end it was the daughter in law who went to the elders in Earnest. They did nothing, so she went to the police. When the police took him away in shackles, a neighbor commented "it's about time, that man has been abusing her for 20 years that I have been next door..." (The daughter in law left the son over it and has never been back to the meetings)(oh and she was told if she took it to the police she would be df'd....that never happened)
If you cannot get an outside institution to help in this, you are unfortunately out of luck with your mom. Some people need to help themselves. Of course you could take a Louisville to him and let him know you will give him a bruise/break for every abusive thing he does to her!
With no belief in God or Bible you could also consider hiring a hit on him. That will make the abuse stop too.....just a suggestion....But might cause you more pain than it's worth...LOL
My elderly mother is living with my abusive brother who has taken every penny she had so my blood boils t hear this. However my mom won't talk to me, you have your moms ear.
