I think it matters if it was an attempt to direct the investigation toward a location where the person doing the directing was confident the Haleigh was not longer at. What makes it relevant is the consideration as to how and when that person would obtain that confidence. JMHO
Oh, I see now.
I don't know... it seems to me that if she was there at all it is most likely she was removed almost right away, before LE descended on the area. Because if she was there all the time, why didn't the search dogs track her scent there?
And I don't really understand why the family would have wanted LE to look at the dumpster if they knew she if she had been there and had been removed.
I mean, I completely understand a distraught family member pointing out this and that and harassing LE officers with "Have you searched here? There? Why not? Do it ASAP! Do I have to search it myself?" in the hopes of finding her, but if the purpose was to not find her, then it's not clear to me.
If LE had overlooked it, what would be the point of pointing out the dumpster and risk that they find some incriminating evidence? They couldn't have known how thorough it was going to be. Why not just leave be and thank the criminal's good fortune that LE overlooked the dumpster in the first place? Was there something planted in that dumpster that they wanted found?
Also, with the police presence and the media, the family, all the curious onlookers and well-wishers camping around there, and the neighbours surely being a bit jumpy, it would have taken some serious guts to have removed a body that had been there for some time and had to have started the decomposition process by that time. Handling a decomposed body would be very unpleasant and possibly leave a tell-tale scent track to the vehicle used in the removal.
It might have been interesting to have the cadaver dogs to go through all the vehicles some time after the disappearance, to see if anyone had moved a body lately.
