My moms car was hit in a parking lot, how to handle?

[Stonedcl]

My mom was shopping at kohls here in NJ. Whe came out and her whole back bumper and part of the quarter panel was scratched up. She is defiantly need a new bumper and maybe a quarter panel. She went back in kohl's and they called the cops. While my moms was waiting for the cops she was wondering how no one saw this as she was the 3rd spot from the front and then she realized there was a note on the windshield. The note said I saw a white ford focus side swipe your car and the plate was XXX-XXX. The cops came and made a police report took her phone number and said they will search for the car that hit her. My question is do you think the pd will activly look for the car that hit her? If they do find the car and the person does not admit to it then is she going to have to pay the deductible? Has anyone ever had this happen to them before, and isn't leaving the scene of a accident a big ticket like 6 points?

I am just wondering if she should wait until the pd find the person (if they even look) or just go ahead and get it fixed now regaurdless?

Thanks..
