If you spend $100,000 that you know is not your money, you should expect felony charges.
They got what they deserved. They're idiots.
My bank story, early in our marriage, (1980s) I made a deposit and the teller ask, "do your want your balance?"
I said "sure", she slid a piece of paper over, it was a little over $12,000. I said, "that's not correct!: She assured me it was.
I said it's about $10,000 to much, she ask, "are you sure your wife did make a deposit?" I said" yes, I'm pretty sure!"
I didn't argue about it anymore and about 4 days later I got a letter saying "deposit in error, $10,400".
