Silver Yamaha flute with engraved initials on headjoint

I lost my silver Yamaha flute yesterday around 3pm while practicing near the Columbia Public Library on Broadway. It's a silver Yamaha flute, standard student model, with closed-hole keys, and the lip plate has my initials 'AP' engraved. The case is light blue and has a small dent near the foot joint, easy to spot. This flute is sentimental—the last gift from my grandmother—and I’d be grateful to get it back.
