It wasn’t 10 times the lethal dose and it wasn’t enough to kill three people either.
I have no idea why some of you insist on passing along information that is demonstrably false, but this is the second time.
He was killed because of the neck compression according to BOTH autopsies.
The Second autopsy is just lies.
Also, "neck compression" won't kill anybody. We've had several people recreate the situation, and a man can lie on the ground for 10 minutes with someone's knee on their neck, and it will not kill them.
So *YOU* stop spreading false information.
