When Anna Nicole Smith first died, there were whispers that she had been so heartbroken over her son’s death just months before that she had taken her own life. But Seminole Police Chief Charlie Tiger soon put that rumor to rest. “We are convinced, based on extensive review of the evidence, that this case is an accidental overdose with no other criminal element present,” he said at a news conference announcing Smith’s autopsy results on March 27, 2007 (via CNN). Still, the sheer number of drugs in her system was hard to ignore — she had ingested a lethal drug cocktail that included a dozen different medications either before or at the time of her death (via ABC News).

The Broward County Medical examiner at the time, Joshua Perper, confirmed that in addition to the prescription and non-prescription medications, Smith also had three antidepressant or anxiolytic drugs in her system. According to CNN, toxicology reports also found human growth hormone and chloral hydrate — a sleeping drug. The combination of this massive amount of drugs basically shut down her respiration and circulation systems, Perper said. “She didn’t suffer,” he noted. “She went to sleep.”

But the most disturbing fact about Smith’s death is that her autopsy revealed she had been receiving shots of either the growth hormone, B12 vitamins, and/or prescription drugs. And when a needle punctured an abscess in her buttock, bacteria was allowed into her bloodstream and caused a high fever shortly before her death. Perper believed if Smith had received treatment for the fever and infection, she probably would have lived (via CNN).
