So how exactly was Benazir Bhutto killed!? (MERGED)

Re: BB's death was not caused by bullets or bomb fragments

I mean if family don't want autopsy done, they wont do it.
I mean even if doctors find out how she died I don't think they would make a mistake of going to press by them selves.
Or they would be having their own autopsy done.
I would doubt if benazir immediate family won't know who killed her.
But nothing is going to happen like zia's or liaqat ali's.
