Black leather Samsonite briefcase with KC initials

I lost my black leather Samsonite briefcase yesterday around 3pm near Grass Valley's Main Street, right outside Briar Patch Coffee. It's a 15-inch briefcase with sturdy silver hardware and a small scuff on the lower corner. The inside has a red lining and a metal plate with my initials 'PN'. There's a laptop charger and some client files tucked inside, plus a slim notebook. I really need it back for work—it's not just stuff, it has my daily tools and deadlines depend on it.
