My stepson stole my diamond (worth $1200/passed down from my grandmother) and pawned it for $50 to buy drugs. We got him to confess and tell us which pawn shop he took it to. It's been 60 days since he pawned it. They refused to give us any information about who they sold it to - just said too late, it's gone. If I file a police report, will the police have a better chance of obtaining this information? Do the pawn shops by law have to keep a record of who they sell something to?
