Lost brown leather backpack with distinctive white front pattern containing a laptop, documents, and water bottle near Mill Creek Park in Youngstown.

I lost my brown leather backpack with a distinctive white pattern on the front while I was walking my dog in the Mill Creek Park area in Youngstown. It had my laptop, some personal documents, and a water bottle inside. I realized it was missing when I got home, and I've retraced my steps but can't find it. I'm really hoping to get it back soon as it holds some important items.
