Since it certainly looks like your ex committed a crime, law enforcement should be more activeand perhaps you can find a way to persuade them to try harder. Since you know about your ex's use of your son's social security number on his tax return, you might very well know in which state he is living. A good private investigator can help a lot. Such people often know how to trace people through, for example, various state departments of transportation (lots of people have California driver's licenses). There are probably lots of other techniques to find someone.
