A joint one only because your death is between you and your higher self. I say every death is a suicide because you (we) are the ones who choose what our thoughts, feelings and emotion are and those equate to your vibration and that equates to what you attract. So if you die of cancer, or get run over by a truck, or drown, or get shot in the post office while standing in line to pay for a roll of stamps, its your creation and therefore your suicide. 

 Ah, the wonderful paradox of free will
