Once a police report is filed, it's up to the county prosecutor whether or not criminal charges are pursued and what those charges are. If charges are filed, it's up to the defendant whether he pleads or goes to trial. Either way, what he is sentenced to depends upon what the prosecutor decides to charge and, assuming he admits or is found guilty, how the court decides to sentence him. There's no way to predict. Unless your son is legally insane, which is unlikely, he knows the difference between right and wrong and eventually he's going to try to steal from someone he doesn't know...I've seen it enough times to know it happens and when it does, it rarely turns out well.
