I am really sorry it happened to you, and wish you and your mother lots of resilience.

The following is very naive...

I have no experience in this, but since you're working in the banking system, you may know someone who knows someone etc ? It may go high enough that "something" happens, be it some help, or green light for a project to prevent scamming or anything really.

Where I live, banks have to control wire transfers, so for instance if someone wires money for "Brad Pit's kidney", the bank must prevent this. Actually it's a real case, and an undisclosed deal was made between the victim and the bank. Maybe there's something like this where you live?
