Yamaha silver trumpet with dented bell

I lost my Yamaha silver trumpet yesterday around 3pm. I was at the Mall at Sierra Vista area behind the movie theater on Fry Boulevard when I must have set it down. It's a standard B-flat Yamaha trumpet, about 23 inches long assembled, with a small dent in the bell and a slightly bent third valve slide. The case is black with a red lining, and the lid has a sticker with a sunburst design; inside the case I kept a Bach 7C mouthpiece. It also has initials engraved on the bell 'P.P.' I’m really hoping to get it back—this trumpet belonged to my late grandfather and it means a lot to me.
