It is hard to imagine a valid reason why your sister gave that debit card to an unauthorized person. If she knew that person was going to steal money, she might be guilty of a theft, the same as the person who took the money without permission.
It would be similar to having the key to a department store because you work there, and giving that key to someone so they could go in a rob the store. You would undoubtedly be found guilty, also.
Of course, it is dependent on many different factors. What I am giving you is my "take" on this with the facts that I have.
I am sure it was for criminal intent that the debit card and pin were passed on. Would each transaction be a felony?
Thank you very much for your prompt answers.
This is a great service.
