OK, I have constructed a scenario where this might work. First you need an airtight or near airtight room. Then run a fan with some electrical issues so that it produces a lot of ozone. Now ozone is good way up in the atmosphere, but bad to inhale a lot of. Now add in someone with a condition like asthma, really bad asthma, and maybe that person could die? I don't know, it's better (for me) thinking that I have reached a new plateau of the dumbest thing I have ever heard.
