Looks to me like there are several sources for the photos. One is a Facebook page from the English Language school in Cambridge..then other the Saudi paper. ???? I think..so much info coming out it is hard to keep up.
I thought Shoebat was the one that got the ball rolling, and then Pam Geller put it up on her page, sourcing Shoebat.
Both of them had that same photo of her in the black dress.
Just an observation. She certainly could have changed clothes, and/or may not have gone to the two hospitals back to back.
The one thing I am certain of is that she wore the blue dress to the memorial event.
