The good news is that if the police found nothing, no criminal charges will be filed. What is left is a civil case. If you have auto insurance, turn the claim over to your insurance carrier and they will defend you and your son.
All of my colleagues are correct in their advice. If your son did not have insurance, you or your son will have to find a good defense attorney to help your son out. You did not state whose car your son was driving or if their was any insurance coverage or what your son's age was and whether he lives with you. Make sure whoever you talk to (depending on whether your son was covered under an insurance policy or not) you tell that attorney the answers to some of my questions.
The above is general legal and business analysis. It is not intended nor construed to be "legal advice" but rather it is analysis, and different lawyers may analyze this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I have been licensed to practice law in California since 1978.

IF YOUR SON HAS HIS OWN INSURANCE OR IS INSURED UNDER YOUR POLICY, TURNE THE CLAIM TO HIS OR YOUR INSURANCE COMPANY. BEST OF LUCK.
