If this person or gambler could do this kind of thing just to feed his addiction, then I think this person really needs some help because she is ready to commit a crime just because she can't control herself from doing gambling and not just committing a crime. The crime is so big that it could put her in jail for a long time. Well, it's her fault if she is fined or locked in jail; she deserves it. She should know her action before doing anything like that. This story is common, and many gamblers are also committing such crimes. To steal money from someone, I manage to know the feeling of not being able to control myself because I also experience being addicted to gambling, but thankfully I manage to change before it's too late. So gamblers out there, you already know that you are being too addicted to gambling then dont make anymore crime that could mess your life more.
Most of the time though, help is late, like in this case, he has committed crimes and just image if the banks didn't investigate or the victim didn't report, she might continue to do it until she was caught.
However, as far as her going into jail and spending time, not really sure about it, probably 2-5 years and then under probation and then they will seek for her to rehab and obviously she had learn from her mistakes and could really change for the better as she could bring shame to her family with her crimes. And as much as we advise gamblers not to commit crimes, it's very hard for them specially like in this case, she is addicted already.
