It would be the 4th of 4, not the 1st. I've looked at that video and cannot see it. I thought I remembered seeing her scrolling her phone when I watched it live the first time. I may still have it on the DVR. It was the C-Span feed.
One other thought may be that we need to be thinking outside the box here. Getty has that image.
Have we tried web archive to see if they posted it originally without the PS?
Another thought, there are surely closed caption, fixed angle security cameras in there. Check those?
Was there a high-res panoramic photo taken? There usually is one.
