Been following from day 1, rarely posted however. If it is her, I think it was immediate disposal. I study maps and geography and how they relate to crimes, and if often tells us just as much, if not more, then any other kinds of evidence. Particularly in missing person cases, which is what I study most frequently.
As such, this is clearly someone local to the area, most notably Tempe or surrounding areas. He would have had knowledge of Dutchman State Park and knew the wide expanse of the area, but not so much knowledge to accidentally place the body on someone's property. It appears he drove her out the wide, rough terrain, thinking it was very remote and not often traversed, but erred in placing the body on someone's property. So it seems like this person knew of the state park, probably has been there a few times, but not directly local to the park. As I said, more likely local to Tempe.
Now this person would have to resources and time to be missing from 5am-8am approximately, based on video, phone records and distance from Tempe to the park. So he would be in a situation where either he does not have a wife/gf/family or someone who has easy excuses to be missing and unaccounted for at that time. Further, he would also likely to need to have his car cleaned immediately and probably would have his clothes dirty, with dust, dirt etc from the terrain of the location where her body was found.
It certainly does not scream out any person from the party, i.e. college kids and something happened to Adrienne at that party. This was a concise, clear decision, it doesn't feel like a panic move to get rid of a body, as I think it would be if it were young college kids at that party.
I hate this day.
