Few American entertainers have remained as instantly recognizable as Marilyn Monroe, and the circumstances surrounding her final hours have been examined repeatedly for more than sixty years. Official investigations produced a clear ruling, yet certain medical details recorded at the time still draw attention. One specific detail from the autopsy report has often been misunderstood or taken out of context, leading to speculation that continues today. Many discussions focus on isolated lines from medical documents without explaining how forensic conclusions are actually formed. To understand why this case still generates debate, it is necessary to look carefully at what investigators documented, how toxicology works, and why visible findings do not always tell the full medical story.
