From what i read on some old threads, Kyle went to L.E. after Somer went missing, to let L.E. know that Somer had approached the workers that day. ? to clear himself, thus covering all aspects? That L.E. had DNA tested 3 of the workers on the site that day? That they were supposedly all cleared of involvement? Is there anything anywhere to say they were definitely cleared? The helper there that day was apparently also named "Kyle"????? A diversion???
Also if J.H. did commit this crime, we are not aware of that yet, only the child 


. charges, then i guess we could assume the killer/killers still out there somewhere? Probably long gone by now too! They would be stupid to stay around.
From what i understand, these kinds of perps rarely commit that kind of crime in their own home, too much trace evidence for L.E to find. They normally do this in an isolated place, out in the open somewhere! Then again, there are always exceptions to the rule.
If Somer was raped i am sure L.E. have that DNA, and can match it in their data base to try to link it or get that DNA for a suspect in this case. With that, they should definitely be able to get the right perp that did this.
Could Somer have been directly placed at the landfill after the fact?, rather than elsewhere first, another theory.
