Black North Face backpack with fox keychain

Yesterday around 3pm I lost my black North Face backpack near the Rimrock Mall parking lot off West 27th Street in Billings. It's a standard-size backpack, solid black with a red zipper pull and a small fox-shaped keychain clipped to the main pocket. Inside there’s a blue notebook, my laptop charger, and a photo of my dog that means a lot to me. It’s a work-and-school daily bag, and it has sentimental value since it was a gift from my sister last year, so I’d be devastated if it's not found. If anyone picked it up, I’d really appreciate returning it.
