Read the code a little more closely. In short you'll be able to find out who the car is registered to, but without an attorney you won't know where they live. You need legal representation, so either get a lawyer or get your insurance company involved. Address is considered confidential info in Ca, you can't release it just by filling out some form. You need to be a member of the appropriate agency (legal, insurance, law enforcement, car manufacturers).
