Silver trumpet with engraving near Riverfront Park

I found a full-size silver Yamaha trumpet this afternoon around 2:30pm near Riverfront Park's gazebo on Front Street. It has a few small scratches on the bell and a tiny dent near the third valve slide, but it plays nicely. The bell is engraved with 'J.P.' and the blue velvet case has a bright yellow zipper. The instrument probably belongs to a student or local band player; I’d really like to get it back to its owner.
