If there is an autopsy with myocardial infarc finding, than I have to differ to you. It does not change my opinion of suicide. As u seem to know something about the medical fraternity in S'pore, than u will know that they will write whatever they are told to on the death cert.
the likelihood of a women at age 31, healthy otherwise, who does not meet any of the risk groups (i.e. smoker, diabetic, prior heart problems, obese, etc.) suffering a heart attack are tremendously low. Coupled with the fact that she herself is a medical doctor, she would have been the first to recognise the heart attack symptoms, and gotten help.
But you are right that something caused the heart attack. It could be any number ofmedication and it could be self inflicted. The parents were keen to donate the organs, but the time delay was noted for the kidneys not being donated, amongst other organs. Could the time delay be used as an excused because if she took posion, than there is no possibility of donating her kidneys and other such organs. Why was there a delay of 4 1/2 hours anyway? If the parents were informed right away, they would have just said donate every usable organ. they appear to be that type of compassionate people.
