Hello. I'm sorry this has happened and can imagine how distressing it is.
Is there any chance your boy is taking drugs? Why did he steal the money do you think?
I would imagine you have to get him to "earn" the money back by doing work around the house, for example, but the problem obviously goes beyond punishment. He needs to understand that stealing is wrong and unacceptable and it sounds like at the moment he is unable/unwilling to see that and that consequences aren't helping him see that. Does he see a psychiatrist or therapist? This is surely something to take to them if so.
Stealing has many causes. Stealing from a wallet... it's rather obvious, isn't it, and if he is of normal intelligence he would have realised he would most likely get caught. Did he in fact want to be caught? I am just stabbing in the dark here but... there seems to be something more than meets the eye here.
Others will have good advice and suggestions. These are just a few thoughts.
