Black leather Samsonite briefcase with blue tag

I lost my black leather Samsonite briefcase yesterday around 3pm. It was outside the Walmart Supercenter on Blue Lakes Boulevard in Twin Falls, right by the entrance near the bus stop. The bag is about 14 inches wide and 10 inches tall, with a worn leather handle and a small dent on the bottom-right corner. There's a bright blue luggage tag on the zipper pocket and an engraved initials 'P.N.' on the metal name plate. Inside I had a printed presentation folder and a red USB drive labeled 'PRJ-2024'; these are things I really need for work, and I would be grateful to get it back.
