Found black leather briefcase with gold 'J.D.B.' monogram outside The Hungry Horse diner parking lot in Eastern Montana.

I found a black leather briefcase just outside The Hungry Horse diner in Eastern Montana. It was left behind in the parking lot around noon on October 15th. The briefcase is quite nice with a few scratches, and it has a gold monogram on the front that reads 'J.D.B.'. I really hope the owner comes forward to claim it, as it looks like it has some important items inside.
