The media release says the man in CT is carrying a " navy blue school bag" is the one CM OR SC navy blue? The footage from the wooller apartment was so clear...this is very poor quality.
I can't find any good still picks but if you view the video you can get a clear look at the backpacks

SC's back back appears navy blue and similar to the one seen on the CT suspect. In the apartment video CM's backpack appears to be a Swiss Army backpack (you can see the little red flag).
If in fact this is CM captured in the CT store I suspect he switched backpacks with SC.
