Silver flute with engraved initials in case

I'm a college musician, and I’m missing my silver Yamaha student flute. It's silver-plated, about 26 inches long, with a red plush interior in the case. I left it yesterday around 3pm in the Rotary Park parking lot off Main Street in Fort Morgan. The lid has the initials PK engraved on it, and there's a tiny dent on the foot joint. It was a gift from my grandmother, and I’d really like to have it back before recital.
