Lost silver trombone in a soft case with name tag left in the music room at Fort Dodge High School after band practice.

I left my silver trombone in the music room at Fort Dodge High School after band practice on Tuesday. I can't believe I forgot it there! It's in a soft case and has my name tag on it. I'm really worried someone might mistreat it, as it's been in my family for years and means a lot to me.
