Black Samsonite 24-inch suitcase lost near Union Station

I lost my black Samsonite 24-inch suitcase yesterday around 3pm near Union Station in New Haven. It’s a hard-shell case with a few scuffs on the front and a red luggage tag bearing my initials 'AR' on the top handle. There's a small dent on the lower-right corner from a tumble at the curb, and the left-side zipper sometimes sticks when it’s full. Inside I keep a blue packing cube labeled with my name, plus a few essential outfits and a folded umbrella. This bag has sentimental value—it’s traveled with me through several moves and was a gift from my aunt. If anyone finds it, I’d really appreciate getting it back.
