Black leather briefcase with BA initials

I lost my black leather briefcase yesterday around 3pm outside the Starbucks on Main Street in downtown Yuma. It's a 15-inch laptop briefcase, slightly worn black calfskin, with a sturdy brass zipper and a small front pocket. The lower-right front corner bears a brass monogram 'BA' and the interior red lining shows a bit of wear. Inside there's a slim USB drive, a faded photo of my grandmother, and a yellow sticky note on the laptop sleeve that says 'Q3'. The case holds important work documents and my daily planner, so it really matters to me and I’m hoping it turns up soon.
