Papa Tom's creek find

Papa Tom likes to jog along Shoal Creek.  He found a wallet with driver's licenses of two people, debit cards, and credit cards inside.  We found one of the girls on Facebook and sent a friend request and message that Papa Tom had found the wallet.  It's been several days; no response.  I'm guessing she saw my name and because she has no idea who I am, didn't confirm the friend request.  We also tried finding the girls' telephone numbers on the WhitePages website.  Addresses were provided, but no telephone numbers.  Because they only have cell phones?

Not sure what to do now.  Papa Tom will probably turn the wallet in to the police if we don't hear back from either girl.
