Some drunkie hit my father in laws car which hit mine which hit another car last night. by the time i was out there the police had already made a report and towed his car away. front and back bumpers and trunk are all messed up. The police gave me a case number. I didnt get his insurance info and my insurance company wants it. I only have liability so they wont pay for my car. Is there hope? Do i wait or take action?
