Black leather Samsonite briefcase with red interior

I lost my black leather Samsonite briefcase yesterday around 3pm. I was at the east entrance of the Sterling Public Library on Main Street in Sterling, CO after grabbing a coffee at a little cafe nearby. The bag has a red fabric interior and a built-in laptop sleeve for a 13-inch laptop, and there's a small dent on the bottom-right corner. Inside is a notebook with client notes and a white label stitched inside that reads 'Property of Diego Ramirez'. I really need it back—it's my primary work bag and holds sensitive documents and a photo of my kid.
