Tryptophan. They just *LOOK* dead.

Which, incidentally, has been my argument for ages. Why no
Thanksgiving deaths? Incidentally, anyone got a link to an online
article about someone killing himself with CO from a stove during
a power cut?

Must be fuel-burning so that would automatically rule out electrical
heat. You get gas furnace deaths from CO all the time, so the
possibility of that would at least exist from gas stoves.

An interesting general article is at
http://www.healthyindoorair.org/October_CO.htm
They do specifically state in PSA #2 that gas stoves should be looked
at to make sure venting isn't blocked (probably the main reason people
don't fall like flies on T-giving is that the overwhelming majority
actually work properly).

The CDC did a review of non-fatal CO poisoning in the US and they did
find some (4.9%) of these related to gas-stoves and ranges. So if they
were bad enough to come to the hospital ED, they could be bad enough to
croak, it is just that the study wasn't looking at that.

Short answer appears to yes it is probably possible.
