@MassGuy , if you think dismemberment is possible, do you think he got the idea from the Khasoggi's murder? It was on all channels, and recently. All he needs to do is to run across the story when the body is not found, and follow the script.
(In fact, CW's story should have served as a deterrent). But instead, some people would probably think, "how do I avoid CW's mistakes"?
One, he did avoid, or tried to. He bought time. Found the day when people are busy, or away, and wake up with headache the next day.
Next thing is how to hide the body.
He is a local. He might know the habits of the animals, or where
not to hide. He probably has an idea where the police might look first. I bet he knows about cadaver dogs. He knows the terrain, he knows his farm. He doesn't understand the people that well.
Now he knows about Google searches. (After CW's case). He does not know that much about the computers and cellphones. He knows enough (maybe from unsolved/disappeared cases?) to lawyer up.
So to understand where he hid it, one should think like a local farmer. I have no clue. Have some ideas, but don't want to post them. They are probably wrong as I am not a farmer.
If dismemberment happened the plan was not to scatter parts around. The plan was to make it all disappear forever.
