Answer 1

I used to work for an industrial gas company. At a plant that made pure liquid nitrogen and nitrogen gas, all the plant staff knew that if you wanted to get rid of your wife, you’d put a mask over her face while she slept and valve in nitrogen gas. Almost undetectable by an autopsy. We were told that nitrogen is a special gas that shuts off the human brain and nervous system like a switch. I believe detectives are on to this method by now.
