If you saw the ENTIRE video, you would have seen her slump down between the seats, and then a trickle of blood starts flowing on the floor, turning into a POOL OF BLOOD. Jeezuz.
I would be very interested in seeing the entire video. Where is the link? I clicked the two links at the top of the article, and there are no links on this subject here in the comments, or that I could find looking at the top links.
I have been sent the link to the video and seen her slumped down between the seat and barrier, and the blood flowing into the walkway. Also the fact that the people nearest to her did not go to her, but others more distant did try to help her. As to the motives of those who did nothing, they may have been afraid, and the killer did come back for a second look.
