I just saw the new pic on Reddit.
Personally, I don't believe it's her. While they do look similar, they don't look like the same person to me.
I would also be very, very, VERY cautious of anything you see on 4chan. That site has had several similar 'pranks' (the Emily Sanders case is the first that comes to mind). The other pictures purported to be of this girl have never been released - so why would some random guy on 4chan have it? And lastly, if it was legit, then why would anyone post that info on 4chan, of all places?
