Colorful Melissa & Doug wooden train set with tracks

I lost my daughter's colorful Melissa & Doug wooden train set yesterday around 3pm near the Columbia Center Mall in Kennewick, Tri-Cities. It's a 12-inch long engine with four cars, painted bright yellow with blue and red accents, and it shows a bit of wear from daily play. The engine has a small dent on the front and a white star sticker on the caboose, plus a tiny green heart sticker on the tender. It was a gift from grandma and has sentimental value; I really need it back. If anyone found it, please reach out - I'd be so grateful.
