None of my attempts to reach this guy have yielded anything. I posted signs where I found the wallet that say GLEGORY COSTA [yes, it's really spelled that way]! I found your wallet--please contact me at [number] to verify the contents so I can return it to you.
Obviously I'd rather this guy get his wallet & all contents back. That's what I fervently want. But if I can't find him at all, then what?
