answer:Good for you for attempting to return the wallet to the rightful owner. What about contacting the emergency number on one of the bank cards? Let them know the situation. Hopefully, they will reach out to the owner to let them know. From a security aspect, the bank card company may just advise you to cut up the card and throw it away. This happened to me once when I found a card on the sidewalk. At least they had the opportunity to follow up with the owner, even though situation was not resolved on my end. You might get a bank card agent that understands your desire to return all belongings to the rightful owner. It that doesn’t work, how about contacting the local police department?
