Black leather briefcase with red interior

I lost my black leather Samsonite executive briefcase yesterday around 3pm near the Forum Theatre on Washington Street in downtown Binghamton. It's a sturdy, mid-sized briefcase with a small dent on the bottom edge and a brass nameplate on the front that reads 'A.R.' The interior is a red fabric lining, and I tucked in a USB drive with some work files and a few travel photos. It has sentimental value because the briefcase was a gift from my late aunt. If anyone found it, I’d really appreciate getting it back—my key documents and the drive are inside.
