Autopsy and toxicological analysis
After two weeks of intense media speculation about possible causes of Ledger's death, on 6 February 2008, the Office of the Chief Medical Examiner of New York released its conclusions, based on an initial autopsy of 23 January 2008, and a subsequent complete toxicological analysis.[9][10][101] The report concludes, in part, "Mr. Heath Ledger died as the result of acute intoxication by the combined effects of oxycodone, hydrocodone, diazepam, temazepam, alprazolam and doxylamine."[9][11] It states definitively: "We have concluded that the manner of death is accident, resulting from the abuse of prescription medications."[9][11] The medications found in the toxicological analysis are commonly prescribed in the United States for insomnia, anxiety, depression, pain, and/or common cold symptoms.[9][11] Although the Associated Press and other media reported that "police estimate Ledger's time of death between 1 p.m. and 2:45 p.m." (on 22 January 2008),[102] the Medical Examiner's Office announced that it would not be publicly disclosing the official estimated time of death.[103][104] The official announcement of the cause and manner of Ledger's death heightened concerns about the growing problems of prescription drug abuse or misuse and Combined Drug Intoxication (CDI).[10][101][105]
