Black leather briefcase with laptop sleeve

I found a black leather briefcase this afternoon around 3:15pm outside the Ocean Deck Bar on Atlantic Avenue, right near the Daytona Beach Boardwalk. It's a genuine leather briefcase, about 14 inches tall and 10 inches wide, with a small scratch on the bottom corner and a silver latch. There's a built-in laptop sleeve that fits up to a 13-inch laptop, and inside the top pocket I found a navy notebook with gold-embossed initials 'J.M.' plus a stack of business cards from a firm named Horizon Partners. There's a faint coffee stain on the front. I'd love to get it back to the owner.
