Healthy fifity year old man, died after a quarrel at Jurong carpark. A motor came in while he was washing his car. He accused the motorist of making his car dirty as he had cleaned the mat on the seats which had became dirty after the motorist arrived. They have a quarrel when suddenly, the man fainted, and died immediately.The police are still investigating why did he die. His wife said that he was a very fit man and only have a fever and a cold but it was all cured. I think that he must have gotten a heart attack from the shock.
