No, I don't think it was murdered but here is a "rumor" for you conspiracy theorists out there:
We all know that Elvis faked his death and moved to Lansing, MI, right? Well, he finally passed for real (he was in his 70's). This opened up a spot at the "home" and MJ is moving in; so, those of you in MI - keep you eyes open, you may run into him at the grocery store, just like you did with Elvis.
I've given up listening to the MJ news. I wasn't a fan when he was alive and his passing really didn't effect me.
