Brown leather Samsonite briefcase with red zipper pull

I lost my brown leather Samsonite briefcase yesterday around 3pm near Seabreeze Mall on Oceanview Avenue, South Coast. It's a medium-sized case with a few scuffs, real leather, and a silver-toned lock; the main zipper has a bright red pull. On the front, there's a small circular green sticker with my initials 'PP'. Inside the gray lining, there's a USB drive with old family photos and a folder of travel documents; the pocket also hides a faded postcard from Lisbon. It was a gift from my grandmother, so it has sentimental value and I really need it back. If someone found it, I'd be grateful to hear from you.
