Fingerprints

We took someone to church Sunday, and while at church, her purse may have disappeared from my car. Nothing else went missing, so it's also possible--in my opinion, likely--that the purse is still in her apartment. I nany event, she reported it stolen and an officer came out to try to take fingerprints off my car. This involved using a miniature feather duster to brush black powder onto the window and door handle. No prints were found--evidently they don't last long.
The fingerprint powder stain, however, lasts quite a while.
