Keys on black ring with dragonfly charm

I lost my keys yesterday around 3pm near the Weatherford Hotel on Aspen Ave in Flagstaff. They’re on a black leather key ring with a green dragonfly charm and a tiny silver USB drive sticking out. There are two brass house keys and a car key with a chipped red plastic head—the ring is a bit worn from daily use. The dragonfly charm was a gift from my grandmother, so it feels really important to get them back. If anyone found them, I’d be incredibly grateful—these keys unlock my apartment and my work bag, and I was supposed to start a shift this evening.
