I believe people commit suicide in unusual ways all the time. In my opinion, a suicidal person is already not quite thinking straight and their mind is tormented. I believe because of this, unusual suicides happen. Who really knows what a suicidal person is actually thinking at the time they take their life. How much sanity is included in their thoughts cannot be known. Most likely, their thought process is not sane. As unusual as Rebecca's death was, I don't find it hard to believe a person may commit suicide in a similar manner. I don't question a suicide could happen like this. I question the story we have been told, the lack of evidence, missing pieces, pieces that don't add up and the poor investigation to support the conclusion Rebecca's death was a suicide.
In a suicide, I wouldn't expert there to be a lot of evidence of a homicide. I don't agree that RZ's death investigation was a "poor" one. It involved many agencies working together.
