A guy scammed me, but he gave me a bank account number & routing number. Can I use that to take out what he owes me?
As long as there is nothing more to this story you aren't sharing, you can expect those bills you paid to come back (you will have to pay them again later). You can be pretty certain that the name he gave you was fake, and that the bank account you paid your bills with was not his. I would not try to do anything at all with the information he gave you because first it is not his, and second your name is already tied to this bank account via your utility bills. In other words that would be illegal and you are already on the list of suspects.   I would say that if you don't call the police they probably won't call you. The police often times do not even waste their time when somebody's light bill was paid with fraudulent financial information or whatever. I have actually seen similar situations play out a number of times and the police have never gotten involved. Disclaimer: I probably don't live where you live, and I'm not an attorney.  But I do know what I am talking about so here's my advice (I know you didn't ask for advice but you probably might benefit from it). Let that money go, sometimes people get you. Take it as a lesson and move on.  If you do end up having to have contact with the police and you don't already know, they will lie to you and try to trick you into acting in a way that is not in your self interest. But then you kind of look guilty if you won't even talk to them, and in this case you did not do anything illegal. So if I was you I would probably just think of where I might be incriminating myself by telling the truth, if there were any parts of my story that would raise any flags, and think of how I would smooth those out ahead of time.   Also for your personal information you do not need to have a sophisticated understanding of computers to do anything you described, if you are familiar with operating a web browser you can do all types of stuff with Paypal. Most people that give off the vibe "criminal" are not going to be able to make any money conning people and would probably have given it up before they got to you. The information you have is not like the most valuable stuff ever but somebody that knew what they were doing could use it to take money out of your account, and if they had that and then could get a few other pieces they could really mess up  your life. So that's part of why they say to be careful, any one piece is maybe not so valuable but if you are loose with everything you will probably have a shitty few weeks at some points in the future. "no aa" lol
