Michael Jackson and Needle Marks

In my opinion, if Michael had taken the drug Diprivan there would be needle marks on his arm. It is my understanding the drug has to be taken intravenously. If any needle marks were found by the coroner, he/she would have told it and if not, yet another Michael Jackson news cycle hoax.
As always,

P.S. Why haven't we learned the story and name of the fourteen year old survivor of the plane crash wherein all 152 passengers died? Curious.
