There has to be a certain reason, if some witness/es say, BG looked like a young man (NBG) and some witness/es say, BG looked like an older man (OBG), but the body was described as the same (height/weight/proportion/perhaps even clothing). Perhaps that was "the twist", of which we heard early on in the investigation? If the head was different, but the body wasn't, then maybe it was a perp with a doppelganger (

) or a perfect lifelike mask could have been in the play, although a little bit absurd (as absurd as the whole murder case seems). Nobody
knows of a mask, but one can think about it at least. Might have a been an image of a buddy, for example, someone with a beard. The video, Libby taped so very well, shows in it's stills a different image all the time: BG
with shadow like a beard, BG
without shadow like a beard, BG
with bulky nose, BG
without bulky nose - so the face in this video isn't recognizable really. MOO
