The topic I have chosen to the frame is Marilyn Monroe’s death. What impact did Marilyn Monroe have on society after her death?

Or I could possibly ask: What impact did Marilyn Monroe’s death have on Hollywood? Did Marilyn Monroe take her own life or was it homicide?

I am not sure exactly sure if the way I have framed the question is too broad.

I am also concerned that I may have a difficult time finding credible primary sources.

I would really like to do the question: Did Marilyn Monroe take her own life or was it homicide? However, I think there might be more conspiracy theories than facts. But, there are primary sources that have posed the homicide aspect… Not sure what to do.
