Sunburst Yamaha FG800 acoustic guitar

I lost my sunburst Yamaha FG800 acoustic guitar yesterday around 3pm near the MSU Library on Stadium Road in Mankato. It's in a black hard-shell case, and a red guitar strap with white stars is attached. The guitar has a small dent on the lower bout and a sun-shaped sticker near the soundhole. This guitar is sentimental—my grandfather bought it for me before he passed—and I really need it back.
