Black RFID passport holder with red trim

I found a black RFID-blocking passport holder this afternoon around 4:15pm outside the Rhode Island Convention Center on Dorrance Street in Providence. It's a slim faux-leather case with a red zipper pull and a small scratch along the bottom edge. Inside there's a couple of cards and a boarding pass, and I can see initials 'J.S.' embossed on the inner pocket. It looked like it belonged to someone traveling, and I hope it finds its owner soon.
