How do you find the insurance information for the registered owner of a car?

The Person driving the Car that hit our car gave the officer HIS policy information. NOT the registered owners policy information. When I called the Insurance agency They told me They do not have that Car on ethier of ther policys and that Her *the Registered person for the car) was canceled but there was never coverage for the car that hit ours. So We are left with Trying to find out Where if she is at all Insured at so we can get our car fixed. Is this possiable without calling her. I do not want to call them after all ifyou lie to the cops why would you tell a stranger the truth?
