Same wideload as thge balloon female in the bomb-day footage, but the hair is different. However, the female leaning against the building beside whom the balloon female stops DOES fit the scant imagery in the UK photos. I can’t tell exac tly how the balloon carrier has her hair fixed. It appears to be shorter than the white pants feamel from UK photos. BUT a wig could bundle that shock of hair up for a stroll down Boston streets. The sure bet is that several animals were involved int eh bombing, not just Mutt and Joker. I am becoming convinced that the balloons probably carried the radio control signal to the second bomb.
Balloon woman may be wider, heavier (and shorter legs?) than hand-cuffed woman. Look at balloon woman's haircut as she walks down the sidewalk. Odd, but unfortunately, so blurry.
Striped-shirt woman may fit the description. We need better photos. I thought FR posted some stills of balloon woman.
for the BTW: Here is the link for the photo in post 26:
