Gold Yamaha alto sax with blue strap

I lost my gold Yamaha alto sax yesterday around 3pm somewhere near the parking lot behind the Civic Center on Zaragoza Street, in Laredo. I had it in a soft black case and remember it slipping out when I paused to tie my shoelace at the crosswalk. It's a gold lacquer horn with a few worn spots, a tiny dent near the bell, and the blue neck strap with a white Yamaha logo attached. The bell is engraved with the initials 'D.M.'—a detail you can feel when you lift it. This sax means a lot to me; it was my grandmother's gift and I really need it back for band rehearsals.
