The question is about whether Kuina's death is as it was originally explained or whether there is something more going on in the One piece manga.

In chapter 5, we are introduced to Zoro's childhood rival Kuina. Zoro and Kuina make a promise that one day one of them will become the worlds greatest swordsman. The day after, Zoro gets told that Kuina has died in an accident, falling down some stars. A lifeless body is seen but with part of the face covered by cloth.

There are many theories about whether Kuina = Tashigi which would make the statement False. Also it is quite a strange way to die for an 11 year old combat prodigy.

In order for the statement to be True, the following things has to be true

• Kuina really did die

• It was in an accident related to the stairs

So in case the truth is that her dad pushed her down the stairs intentionally, the question will be resolved to No.

If no further info is given until the official end of One Piece, I will resolve the question to Yes.
