Mom should be out of the house.
OP, you do not want her to know you called and/or turned her son in.
People are funny. If it goes sideways and her son gets hurt, she will blame you. Be very careful on how you handle this. Definitely do something, but do not keep her in the loop. You risk full backfire in your face.
