Water is not toxic.

That is a really bad description. If one puts a saltwater fish in freshwater it will die as water will enter the cells and dilute the essential chemical reactions that keep cells alive. Some cells may even burst. But water is not toxic by definition. Very strange.

Her bladder may have ruptured and she may have died of internal hemmoraging... her kidneys which control water balance could have bled, or something like the aforementioned fish, but toxic? Nopes. I feel bad for the woman, but the article says they are waiting to determine the cause of death. Very strange.
