Kid's Spider-Man Halloween costume with mask

Found this kid's Marvel Spider-Man Halloween costume this afternoon around 3pm, in the parking lot behind the Jacksonville Landing along the St. Johns River near Main Street. It's a red-and-blue jumpsuit with a Spider-Man emblem on the chest, and it comes with a plastic mask and web-print details. It shows light wear—a small dirt smudge on the knee and a tiny seam snag—but it's otherwise in good condition. The costume looks like it would fit a child about 5 to 7 years old. If you're the owner and can verify a couple of identifying features, I can meet up to return it.
