3 year aniversery of Michael Jackson death

The three year aniversery of Michael Jackson death is coming up and the reason I bring this up there still questions as we all know Conrad Marray is gulity but I think there is more evidence to it like where did Conrad Marray got hired and where did Conrad Marray got the huge propol to kill the king of pop and also where did the propol was made in a company or in country and should Michael Jackson not hired him those all the questions need to be answer!!
