Black leather briefcase with red interior

I lost my black Samsonite leather briefcase yesterday around 3pm near Union Station, along Wynkoop Street in downtown Denver. It's about 14 inches wide, with a brass latch and a noticeable scratch on the lower corner. The interior is a bright red lining, and I still see a blue spiral notebook with my initials 'A.K.' written on the cover sitting in the front pocket. It also holds important documents and my laptop charger, so it means a lot to get it back. If someone found it, contact me at [email protected].
