Here are some people who took their last breaths in the bathroom. I got these from The Bathroom Reader (a very entertaining and funny book):
In 1016, 27-year-old King Edmond II of England was murdered in the bathroom by an assassin who hid behind his primitive toilet. As Edmond sat, the murderer stepped out and shoved his sword twice “into the king’s bowels.”
Movie producer Don Simpson (Top Gun, Flashdance) died in 1996 from what was rumored to be an overdose of cocaine. Actually, he died of a heart attack while going to the bathroom.
Probably the most famous toilet-death was Elvis Presley’s. He died on the pot of a heart attack while “takin’ care of business.” You could say that the “King” died on the “throne”… At the time of his death he was reading a book entitled “The Scientific Search for the Face of Jesus.”
