Black Briggs & Riley briefcase with brass lock

I lost my Briggs & Riley black leather briefcase yesterday around 3pm. I last saw it outside the CVS on Main Street in Poughkeepsie, right by the Walkway Over the Hudson overlook. It's a 16-inch briefcase with a brass lock, a red zipper pull, and a brass tag engraved with my initials PK. Inside there's a grey laptop sleeve, charger, a blue notebook, and a small photo sleeve with my grandmother's picture—this bag has sentimental value and I really need it back.
