Found keys on red lanyard near Riverfront Park

I found a set of keys this afternoon around 2:45pm near Riverfront Park in Spokane, WA, by the Monroe Street Bridge pedestrian path. They're on a bright red carabiner-style keyring with a blue enamel fish charm and a small black USB drive tucked in between the keys. There are about seven keys in total, including a house key with a dented head and a shiny new car key that looks like it might fit a compact sedan. The ring and charms are a little scratched up, but everything seems functional. If you recognize these, I’d be glad to reunite them with you—drop me a note here and we’ll arrange a safe pickup.
