Black leather Samsonite briefcase with laptop pocket

Yesterday around 3pm, I lost my black leather Samsonite briefcase outside the Safeway on West Broadway in Moses Lake. It's a standard 15-inch laptop briefcase with a padded sleeve and a small front pocket; the corners are a bit scuffed and there's a faint coffee stain along the inner lining. Inside are my gray laptop, a red notebook, and a blue USB drive labeled 'Q3,' plus a bright green sticker with my office code in the inner pocket. This briefcase is essential for work and it contains confidential files, so I really need it back—if you found it, reach out and I can verify the features.
