Black Samsonite carry-on with red tag

I lost my black Samsonite carry-on yesterday around 3pm near Union Station in Kansas City, outside the main entrance at 30 W Pershing Rd. It's a 21-inch matte black bag, with a bright red luggage tag bearing the initials 'KP' on the handle and a slightly bent front zipper. There was a small dent on the bottom-left corner and a thin blue ribbon tied to the zipper pull as a personal marker. Inside, I kept a folded travel-sized umbrella, a passport holder, and a laminated photo of my late grandmother—these items give it sentimental value. If found, please let me know; I'm really hoping to get it back since it contains important documents and a few irreplaceable mementos.
