Can we assume that the fact that the backpack was sold exclusively at Walmart is a significant breakthrough? Apparently, Walmart is known for their comprehensive “tracking” of purchasers, even having video of cash purchases.
Also, although the rest of the items could have been purchased elsewhere, I’d think that since they’re also sold at Walmart, and the backpack is only sold there, the perp may have purchased some of the other items there as well,
I wonder how long it takes Walmart to track down these purchases?
