You're making the assumption they were murdered. That's the conspiracy theory I'm talking about and you repeat it without knowing.
There it is again. You're fucked in the head and paranoid. You need help.
I don't believe they hired anyone to kill anyone. It's a classic example of the conspiracy nuts which USA is full of.
Did it ever occured to you they died from normal causes? Why did you assume a conspiracy from the off? There's nothing to indicate it. You're off your head.
