Whether or not the feature seen in the video is a person, or just some video artifact is hard to tell from the resolution of the Youtube version. It is possible that a higher resolution version of the video was provided to the FBI. You can see the video here.

Wild stuff but she is dead and the man she supposedly was head over heels for possibly murdered her AND HE NEEDS TO BE FOUND.
How that lesbian couple's murder is not connected seems odd to me.
Wow. So that couple may have helped find her?
Thanks for the video link, the confluence of events leading to her body being found so quickly was surely divine providence.
