The Los Angeles County Coroner has changed the death certificate for Michael Jackson to include the word homicide, opening the way for a possible murder prosecution.
The singer died on 25 June last year in his Los Angeles home of an apparent overdose while preparing for what was supposed to be a 50-night concert tour in London.
The official causes of the 50-year-old's death are now listed as acute propofol intoxication and intravenous injection by another.
The change paves the way for the prosecution of suspects and the No 1 suspect is Jackson's doctor Conrad Murray, who administered the injections.
Dr Murray has retained lawyers ahead of charges being issued.
The Los Angeles County District Attorney makes the final determination if there is enough evidence to charge anyone with Jackson's murder.
