Gray Jansport backpack with red zipper pull

I lost my gray Jansport backpack yesterday around 3pm near the Old Town Plaza gazebo on San Felipe Street in Albuquerque. It's a standard-size backpack with a bright red zipper pull and a small cactus pin on the strap. Inside are a 15-inch laptop, a blue spiral notebook, and a charger. The bottom edge shows some wear from daily use. It has sentimental value because it was a gift from my grandmother, and I really need it back.
