Black Samsonite suitcase with red tag found

I found a black, hard-shell Samsonite suitcase, about 24 inches tall, with a few scuffs on the corners. I spotted it this afternoon around 4:15pm in the parking lot behind the Fox River Mall entrance on College Avenue, Appleton, in the Appleton-Oshkosh-FDL area. It has a bright red TravelBug tag on the top handle and a small blue dinosaur sticker on the inside lid. The wheels spin and the retractable handle extends cleanly, so it seems recently used. Inside there's a folded map and a spare travel umbrella tucked in a side pocket—small clues that might help the owner.
