Are you intentionally not seeing that which refutes your opinion?
I do not have an "opinion". I have information, and frankly until now nothing you have linked seems to contradict that info.

Otoh, having seen dov's response, I did some googling and found the med examiner data he referred to, which does contradict that info.

And this leads to a bit of a conundrum - how could people be shot with a weapon which appears to have been elsewhere. The answer seems to be that the weapon in the car was actually a shotgun, not a rifle. Hence there was an additional weapon involved.

Had you actually said that, instead of ranting, thing could proceed more smoothly.
