Uhhmmmmmmmmm...........
All of the above and you add in a little UNBRIDLED RAGE!
The body disappearance is because he still believes the old saying, 'No body, no crime.'
He really should read more though. There have been several cases where there was a conviction without a body.
But seriously, during the Laci Peterson case we had a guest here on WS with his own thread. He was a legal person and at the time we didn't know who he was. We would ask questions and when he had time he would reply. No chit-chat on that thread......anyway, we found out a couple of years later it was Chris Darden.
Ok, back to the subject, he said that the reason perps disappear the body is it's the BIGGEST proof that a crime was committed. It's also well known that quite often, a perp unknown to the victim, is more than likely to 'leave the body' where the crime was committed. Moving a dead body is VERY RISKY. On the other hand, someone CLOSE to the victim is more likely to MOVE the body to take suspicion off himself.
I don't think killing Susan necessarily had a monetary motive. IMHO, I think it's more likely Josh was jealous of Susan's success both professionally and personally. She seemed to be a step ahead of him. If you go back and look at many of our previous cases, this is often the case. Laci was much more personable than Scott, Michelle Young was very successful and Jason was just a traveling salesman, Janet Abaora worked and Raven didn't because he was a looser, Brad Cooper was extremely successful in his field and liked to flaunt it and couldn't stand the thought his wife could make it on her own (he controlled her spending as well), Lori Hacking was successful and graduated from college while her husband lived a lie that he was attending college and then med school, in the March case he was a looser who worked for the wife's dad's law firm and was in jeoprady of loosing his job while she was a successful artist ie decorator, home designer (their home being her crowning success)............
I could go on,...............but the point is the wife is outgoing, successful, popular, and in about all the cases I've mentioned except Laci, there was divorce discussions going on. Thus the ultimate motive, IMHO, is control. If he can't have her, NO ONE will!
JMHO

PS............from my friend who's husband attempted to kill her, his favorite saying to her at the end of every argument, "Remember, to death do us part." Seriously, it freaked me out!
PPS.........from someone else I know in such a relationship, he used to tell her he could take her out into the countryside and dump her body and no one would give a dam* and they'd NEVER find her.......
