Dark brown leather briefcase with initials JR

I lost my dark brown leather briefcase yesterday around 3pm near the Janesville Public Library on Main Street. It's a mid-size case, about 16 inches wide, with scuffed corners and a brass nameplate on the front that reads 'J.R.' Inside there's red lining, a small zipper pocket, and a faded blue notebook plus my laptop charger. The zipper pull has a tiny dent, and there's a luggage tag inside with 'JR' written in marker. This briefcase holds important work documents and was a gift from my mentor—I'm really hoping someone found it and can return it.
