It should be noted that a homicide is not necessarily a crime. Murder is a form of homicide, but there are cases that could be ruled "justifiable homicide." However, the designation of Jackson's death as a homicide would seemingly make charges against his personal physician more likely.
The official cause of death was determined to be acute propofol intoxication. However, a combination of other drugs was found in his system, including the sedatives Lorazepam, Midazolam, Diazepam, Lidocaine and Ephedrine. These were listed as a contributing factor.
Although the results of the autopsy were issued, via a press release, the complete toxicology report will remain sealed at the request of the Los Angeles Police Department and the District Attorney.
Dr. Conrad Murray, a Las Vegas, NV cardiologist who became Jackson’s personal physician in preparation for comeback tour, weeks before his death, is currently under investigation. Murray has previously admitted giving Jackson propofol and other sedatives for insomnia reasons on the day he died, June 25th.
