Access to pawn shop records in NJ to see if stolen items were pawned.

Hello. I have strong reason to believe that over the last two years or so, that my mothers jewelry was stolen by someone and pawned at different times in our area, while she was sick and in the hospital and nursing homes. Basically, is there any database to check and see if the persons name appears on any sales records from pawn shops in my area? I thought there was some law that ID has to be given and shop owners feed it into a database for police to use and keep track of reported stolen items. Is there any way I can check these or any other available sales records agains the name I have? This is for Monmouth County, NJ. Thank you for your time and help! Anthony D.
