Silver Yamaha flute with engraved initials

I’m missing my silver Yamaha flute — a starter model in a black hard case. I left it yesterday around 3pm outside the Boulder Bookstore on Pearl Street Mall, near the outdoor seating area. The flute is silver, with a few light scratches and a tiny dent on the end of the headjoint; there’s an engraving 'DM' on the headjoint cap, and the case has a faded red lining. It has sentimental value—it was a gift from my grandfather and I really need it back. If you found it, I’d be grateful to get it home.
