Charcoal Samsonite suitcase with orange zipper pull

I found a large charcoal Samsonite suitcase this afternoon behind the Michigan Theater on Liberty Street in downtown Ann Arbor. It’s a 28-inch hard-shell polycarbonate with a few scuffs on the corners and a bright orange zipper pull that really stands out. There’s a blue luggage tag on the handle with the initials 'J.S.' and a small paw-print sticker still attached. The lining is striped blue and gray, and I noticed a folded umbrella tucked in the side pocket. If this belongs to you, I’d love to help get it back.
