My thoughts
-We have been having snow storms in Alberta (or "third winter" as I like to say) over the past 10 days, on and off, so the snowsuit isn't totally strange.
-The police have clarified that the clothes were found with the boy, NOT on him
-The stroller appears to be empty in those surveillance videos
Thoughts?
Edit:
I think this is there hats (or as close as I can find). I wonder if there is a gang affiliation with them.

I do not easily see a child in the stroller ... need to sharped the image some more.
Not sold on that hat
