I'm with pretty much everyone else, that this looks like Libby. Sad news for her family, but I think probably better than prolonging the agony any longer; I've felt for several weeks that it's very unlikely she could still be alive, so at least if this is her, her family can begin the grieving process.
If it turns out that her death was caused by anyone, I hope there's enough evidence to get justice for her. On the flipside, if it was actually a tragic accident (even if started by someone, eg PR, scaring her), then I hope that could be determined too, although given the length of time, I'd guess evidence of any kind of likely to be slim.
