That is a good question and one they are fighting to get the answers to.
The bank allowed someone else to access their funds is all I know.
My daughter says it has to be an inside job for someone to have gotten all the access info to their accounts.
Granddaughter didn't lose custody totally but has limited time with them as she wouldn't move back to town her soon to be ex lives in, judge ruled they had to go to school there.
I haven't talked to her lately but she was handling things pretty well the last time I did.
Thanks for asking.
