IMO, just because LE says it's not a stranger abduction doesn't mean it wasn't. There is room for error in a LE theory. I have been leaning toward family abduction in Haleigh's case, mostly because there has been no body found, but also I would like her to be alive. But when Somer was found in a landfill and knowing the 3 dogs hit on a dumpster in Haleigh's neighborhood, it made me sick to my stomach. I think it is a very strong possibility that there is a sexual predator/serial killer loose in Fla. LE is very leery of saying this might be the case, in any city, because it causes widespread panic. But it does seem entirely plausible to me.
IMO.
Curve, it could be possible. If a serial killer, then we have to examine whether the modus is getting better or sloppier. In one instance, we could say sloppier, because Haleigh wasn't found, and Somer was. But then we look at technique, and Haleigh was sloppy...so many risks involved in snatching a child in the manner Haleigh disappeared (according to the current story thrust out from Misty et al). Somer was an opportunistic grab; the perp couldn't know she'd get into a fight with the other kids and run off. She was taken from wherever she ran off to, and the perp grabbed her from there.
Serial killers keep to MO...they have patterns, because patterns work for them. They kill in specific ways because they're driven by a necessity to fill a need. One could say disposal of the child is the pattern. But then we have to look at acquisition, as well. We have no knowledge of how Haleigh may have been taken by a perp (in this scenario) but no evidence was found.
(p.s., since the heat in a landfill can become very very high, the possibility of finding anything of Haleigh in one would be nearly impossible. Not a pleasant thought, but it is realistic if one wants to consider a landfill search.)
Having found Somer, LE will have a better idea of what happened. I will not be surprised if they discover that her wounds are minimal but were enough to cause her death, and the perp panicked and hid her in the dumpster.
Because of all the discrepancies between the two cases, I have dismissed the possibility of a serial child killer......for now.
