Black leather briefcase with red zipper pull

I was by the Biloxi Lighthouse on Beach Boulevard yesterday around 3pm when I must have dropped my black leather briefcase. It's a Samsonite case, about 16 inches wide by 11 inches tall, with a sturdy handle and a front pocket that hides a red zipper pull. The bottom corner is a bit scuffed and the blue fabric lining has a faint coffee stain, plus there's a small dent along the back edge. Inside are work papers, a USB drive with family photos, and a note with my grandmother's initials—it all has sentimental value and I really need it back; if you found it, email me at [email protected].
