UDPATE: Good news – keys were reunited with the owner!
Are you missing a set of keys? From the Forum:
Keys were found near my home by a neighbor passing by. If you are missing a set of keys and you were passing through the 4th Ave W/Garfield/Library area today, please email me at email@example.com. Accurate description of the keychain will be needed. If no one claims them by Monday 10 December, I will be taking them to the police station in downtown Seattle.
