Brown leather briefcase with red lining

Yesterday around 3pm I realized my dark brown leather Samsonite briefcase was missing in the Kenosha-Racine area. It's about 16 inches long with a gold-tone latch and a small dent on the top corner. Inside there's a 15-inch laptop sleeve, a red lining, and some client folders; I also keep a faded note with my initials 'MR' tucked in the front pocket. It has sentimental value because it belonged to a mentor who meant a lot to me, and I'm really worried about losing it. The last place I saw it was outside the Starbucks on 52nd Street near the Kenosha Public Library. If found, please contact me; I’d be grateful to get it back.
