First off, I'm sorry. I went down this road with my godmother, $300k still unrecovered, despite lots of information documented.
How did the money actually leave her account once they had access? Was it wired?
Unfortunately the solution for you right now is to focus on rebuilding and acceptance. This is a massive problem, you aren't alone, and it's a reminder that there are shitty people in this world. There needs to be an alert and approval mechanism for outbound wires that older people can be strongly encouraged to set up. Sons and daughters can be notified if there's a massive outbound wire pending and intervene -- scammers are often posing as these people.
