Vitamin "C"

The professor carefully looked at the contents from the deceased's stomach, in less than half an hour, the mystery was solved. The professor said: 'The deceased did not commit suicide and neither was she murdered, she died of accidental death due to ignorance!' Everyone was puzzled, why accidental death? The arsenic is of the U.S. military for carrying rice seedlings H Gao. The professor said: 'The arsenic is produced in the stomach of the deceased.' The deceased used to take 'Vitamin C' everyday, which in itself is not a problem. The problem was that she ate a large portion of shrimp/prawn during dinner. Eating shrimp/prawn is not the problem that's why nothing happened to her family ever though they took the same shrimp/prawn. However at the same time the deceased also took 'vitamin C', that is where the problem is!
