????? He must've been really lucky or there was something in her wallet to give the PIN away (birthday?)
That really sucks...only thing I can say and I'm sure you've already done is to tell the banks ASAP! It's doubly dangerous if they have the pin since it's harder to prove what they withdrew and what your mom withdrew.
Hope they catch the fucker!
Bit of sad news. There was a coworker that I worked with, Marc Hogi, and this dude was a gigantic black man teaching English in Korea. He initially freaked out his students since he was so big. However, he won them over with his friendliness and charm. He was definitely one of the nicest guys I've ever worked with. I remember I was the first teacher he was observing when he first came to the school. He just recently passed away...I'm not sure exactly what happened, but he was one of the last people I expected to pass away so suddenly.
