Somebody with bad training in chemistry is really in a damage control by declaring the deaths of these men as natural! Yes, even of 30ml milliliters of methanol are enough to cause a death, it is required that this be a puree concentration of methanol as in windshield wash or other pure form of methanol. In drinking alcohol, it is assumed that that methanol got into their drinks as form of contamination. In that way, we need to know let a us a how much methanol was in a bottle of 1000ml vodka [we need to know of methanol in terms of vol/weight in 1000ml ] in some other valume. We also need to know the ages and weight of the three men because their body weights should have different and that would have created differential in how their bodies responded to the intake of certain amount of methanol in specific concentration. I am using this scenario to show that the accidentally poisoning has lot of questions unanswered. And then how quickly did the doctors doing the autopsy figured the nature of methanol on the bodies of these men since the chemical composition of a substance change after it is ingested. The most logical way deadly amount of pure methanol can get into the drinks of these three men if was poured into their drinks deliberately. I smell a cover in this shocking incident

It wasn't Vodka. It must be local liquor. We have a lot of methanol poisoned case here in Indonesia. One of my best man in my wedding two months ago also died from it. Some one even post warning in Lonely Planet.
