Black Samsonite carry-on with red tag

I lost my black Samsonite carry-on yesterday around 3pm near the Amtrak station on Leroux Street in downtown Flagstaff. It's a 22-inch hard-shell suitcase, black with a dent on the bottom left corner. There’s a bright red luggage tag and a blue painter's tape repair on the top corner. Inside, there are some photos from a family trip and a small keepsake that belonged to my grandmother. The bag is a little scuffed but still functional. I really need it back; it has sentimental value.
