MOO.
I would imagine the abductor, trying to prevent leaving any DNA from stray hairs, etc., wore fresh clothes to NG’s house. (However bumbling they may be in some ways, they seem to have managed not to leave DNA that got found–and some article said the ransom note bragged about that, though I don’t know if that was validated.) I was initially thinking the jacket was likely to be from Walmart since the backpack seems to be. I agree with others that the overall jacket style is pretty basic–but the zipper is not. It’s got contrasting piping on each side of the zipper rather than the zipper itself being high-contrast. I could not find any like it at Walmart online, with both the horizontal dark line across and the contrast zipper style. But I did find a soft shell that’s sold in Europe that is very similar to that style. I believe Pitch Stone is a Scandinavian brand. I do not know if it’s sold in the US. (I’m an American who moved to Scandinavia.)
