LOS ANGELES, Sept. 1 (Xinhua) -- Late pop star Michael Jackson's death certificate has been amended by the Los Angeles County Coroner's office based on the latest findings about his death in late June, it was reported Tuesday. 

   The Coroner's office now lists in a report his fatal injury as" injection by another," according to popular music site TMZ. com. The update was meant to reflect the L.A. County Coroner's report which ruled Jackson's death a homicide, it added.

    The document also showed Jackson's main cause of death was "acute Propofol intoxication" and a contributing factor was the presence of mulitple anxiety and insomnia medications in his system.

    On Aug. 28, the L.A. County Coroner has officially announced that the cause of Michael Jackson's death is Acute Propofol intoxication. It says "other conditions contributing to death: Benzodiazepine effect."

    Benzodiazepines are a group of drugs used to treat anxiety and insomnia. The manner of death is ruled: "Homicide."

    The Coroner did not release the full autopsy report but a press notice.

    Jackson was pronounced dead after he was rushed to the Medical Center of University of California, Los Angeles on June 25 in the runup to his London concert. His personal physician Conrad Murray admitted to the police that he had administered certain amount of Propofol, an potent sedative on Jackson in order to help him go to sleep. The investigation is still ongoing.
