Black Yamaha trumpet, red-lined case

I found a black Yamaha trumpet this afternoon around 2:15pm in the parking lot behind the Ontario Mills mall on Ontario Center Parkway. It's in good condition with a bright brass finish and three silver valves that move smoothly. The hard case is red-lined inside, and there’s a sticker inside the lid that reads 'Riverside High School Band 2012' plus faint initials 'RB' on the bell. If this is yours, send me a note and we can arrange a meetup to reclaim it.
