The refrigerants used in modern air conditioning have very low toxicity, and very seldom kill, except by suffocation which needs a substantial concentration of the gas that is most unlikely to occur from a domestic sized unit.
The report also claims that several villas or apartments, presumably each with its own air conditioning system suffered the same problem. Even more unlikely.
More likely in my view is carbon monoxide from gas water heaters, or motor vehicles, or a charcoal barbecue. Or even something completely unrelated such as food poisoning or infectious illness.
Inclined to agree, there is more going on here - and the air con theory seems to be the hunch of one other guest being interviewed, rather than any official line, which is very much 'please wait for the autopsy' . Given the symptoms are paralysis and swollen limbs, I concur, it is some sort of poisoning, than asphyxiation . While vary sad I suggest there is very little to go on as yet, It would be better if the DM employed journalists with some critical faculties.
