LOST navy blue North Face backpack with red zipper pull

I lost my navy blue North Face backpack yesterday around 3pm outside Grand Central Market on Broadway in downtown LA. It's a medium-sized backpack, well-loved with a red zipper pull that sometimes sticks, and a bright yellow sun patch sewn onto the front pocket. Inside there's a 13-inch laptop sleeve and a blue spiral notebook. This bag is sentimental to me — it has notes from college and a photo of my family tucked in the main compartment — and I really need it back. If someone found it, I’d be incredibly grateful; thanks for any help.
