Black 25-key USB MIDI keyboard controller

I found a black 25-key USB MIDI keyboard controller this morning around 9:15am in the parking lot behind the Orpheum Theater on S 16th St in downtown Omaha. It's a compact, matte black unit with a few light scratches on the corners and a small orange sticker near the top edge. A blue USB cable is still plugged in, and there's a tiny dent on the right side along with a sticky note that says 'Sam' on the back. I know it's probably someone else's gear and I'd love to help get it back to its owner if I can.
