My Mom Is Caught Up In A Very Convincing Romance Scam And I Need Advice On What To Do.

Texas. I don't know if this is the right place. I posted in r/advice and after 24 hours I did not have one comment.

A few years ago after my dad passed away, my mom began telling us (me, my brother, her sisters) that she was getting married to a high-ranking US military general in Afghanistan who leads US and NATO forces. At first I ignored this or shrugged it off (she says a lot on the phone and I don't really listen to half of it) but when she said he was coming to visit, I asked for more details. General Austin Scott Miller. I immediately googled the name, and the first result was about how he is being used for romance scams. My aunts also called me concerned about the scam. My husband and I worked pretty hard for a few days trying to convince her it was a scam. I thought we succeeded.

My parents were not great with money, and when my dad died, she had to ask all her friends and family for monetary support for the funeral and burial. We raised several thousand dollars for that cost, and most everything was paid for except my dad's gravestone. My mom took $4000 of the money we raised and bought gift cards from Walmart "for the orphans in Afghanistan" because "Austin Scott Miller" runs an orphanage and can't accept $USD. Ugh, this is so dumb! My mom was in her late 70's and is morbidly obese!

Ok, it gets more weird. My mom confronted the scammer, and he decided to play the long game. I think to convince her he's real, he tried to return the money (I think) because my mom was suddenly locked out of her bank. She said when she "tried to deposit a sum of $4000 from a friend," the bank froze her account. They froze it for at least a year. She had to beg money from friends and family to survive. When I ask for details on who gave her the check, she says it's none of my business. So I can only assume it's from the scammers, and the bank picked up on some sort of fraud. My mom is a retired lawyer and is currently suing the bank, so I know it wasn't a made-up story.

A few years went by and my mom mentioned that she was trading bitcoin for people, and I didn't ask details because, I myself want to live in fantasy land where my mom isn't caught up in a romance scam. But new details emerged, and I'm worried that this bitcoin trading is just moving money around for the scammers.

Her friends and sister have recently complained to me that my mom is still caught up in that ASM romance scam. Since my mom has asked us for money for dental work, I confronted her about it on the phone. I asked he, "Do you believe ASM is in contact with you?" Yes, she does, but she didn't want to talk to me about it. As an aside, her sister told me she confronted my mom, and my mom told her they FaceTime regularly, so she knows he's real. I'm thinking that the scammers are incredibly high-tech if they are using AI for video and voice. So I tried to talk sense to her last night but got nowhere. Apparently, there's a fake wiki page somewhere that claims he's divorced. Ugh! I hate this so much!

Anyway, with all these details and bitcoin trading, I want to report this to the FBI, but how do I do that? Will they even care? or who do I report this to? Is there any authority out there that can help?

TLDR: My 82 year old mother is caught up in an Austin Scott Miller romance scam and possibly money laundering for them with bitcoin trading, I want to report to FBI but I don't know that they would even care.
