Black leather Briggs & Riley briefcase with laptop sleeve

I lost my black leather Briggs & Riley briefcase yesterday around 3pm near the Columbia Center Mall on Columbia Center Boulevard in Kennewick. There's a padded 15-inch laptop sleeve inside, and you can spot a small scuff on the bottom corner. Inside are my day planner with a red elastic band, a blue USB-C charger, and a crumpled sticky note with my initials. It has sentimental value—it was a gift from my mentor, and I really need it back to keep my work on track.
