my apologies if this link was posted before. however if you scroll down the article a video will load.
the video is to the left of "video news"
hackett is in the video, if you watch the video you will notice that dr hackett has a problem walking and gets very out of breath. physically i don't think he could chase these girls or catch them due to his physical condition.
into the video (which starts out mentioning divers) go into the video until 1:06 into the video they show hackett walking.
if hackett was the sk, it would make no sense for him to call the family and give himself away. now he's a local there and would know about shannan going missing that night. if he saw her early morning, likely looking sick and distressed, now even in lower light, your having the morning light come into play. if she was in a state where even her body posture looked like she was in distress i could understand that comment.
what i don't understand is why he would say shannan was at his house when she wasn't; he just merely saw her.
now it's possible someone else called claiming to be him, this person would be local and want to divert attention away from his sk self.
as for rifkin and his 3 missing victims; rifkin buried them in 3's.
so if they are rifkin's i'd think they'd find 3 in a close area.
