Black Tumi briefcase with red interior

I lost my black leather Tumi briefcase yesterday around 3pm near Union Station in Denver, outside the Wynkoop Street entrance by the light rail. It’s a mid-size case, in good condition except for a small scratch on the top corner, and it has a red interior lining. There’s a white leather tag embossed with my initials 'P.P.' dangling from the handle, so you’ll know it’s mine. Inside I keep my laptop charger and a few client documents, plus a note with my late father’s initials—those items matter a lot to me. It would mean everything to get it back; I’m really hoping someone picked it up by mistake.
