When the story of these Kazaks being taken into custody first was posted on FR, some poster (I don’t remember who) pointed out that the handcuffed woman pictured in the daily mail story was of the same general body type and build as a woman seen in the surveillance video of the brothers walking to plant the bombs.
If you look at the video here:

you see at the 17 sec. point Djokher passes in front of a chunky looking woman leaning against the wall with a large blue bag and wearing a stripped sweater/shirt. At the 18 and 19 sec. point she seems to begin making a cell phone call. Not for a moment did she turn her head toward either bomber, but she surely saw them.
It could be an innocent coincidence, or maybe not . . . .
I hope the police have tried to identify her and check out what she was doing there.
It would be rather foolish for someone to wear distinctive clothing and stand right in front of a surveillance camera to do something related to a bombing, but foolish or not maybe someone did not realize they needed to be more careful.
I don't recall seeing the Kazaks photo, but I see what you mean.
Also balloon lady who walks down the sidewalk in front of the bombers stops to position herself right beside the lady in the striped sweater/shirt.
I will keep my eye out for Kazaks photo. Please ping me if you find it.
