'King of Pop' Michael Jackson was "murdered", a British newspaper claimed on Sunday quoting a death certificate issued by a Los Angeles coroner.
British newspaper 'News of the World' has claimed to obtain a copy of the original document and an amendment to it.
In the original certificate dated July 7, deputy coroner Cheryl MacWillie does not site the cause of death. But the certificate was later amended on August 31 by medical examiner Christopher Rogers who gives the cause as "homicide", according to the newspaper.
Rogers concludes that the 50-year-old pop icon died from "acute Propofol intoxication" due to an "intra-venous injection by another".
Meanwhile, Los Angeles Police department has finished its investigation into the circumstances which led to the death of the 'Thriller' hitmaker on June 25 last year.
His personal physician Conrad Murray, who is reportedly being considered responsible for the death, has hired a lawyer in case he is charged.
Murray already has a Houston law firm building his defence. Police affidavits say he admitted loading up Jackson with Propofol and other drugs in the hours before his death.
"We are all keeping our faith with the police. We want them to do this case properly and put away the man who we feel is responsible for Michael's death," said a Jackson family source.
On the original July 7 certificate deputy coroner Cheryl MacWillie refuses to give a cause of death.
But after further probes, it is amended on August 31 by medical examiner Christopher Rogers to "homicide".

Hollywood legal eagle Michael Flanagan saved a nurse from a murder charge when she was accused of wrongly administering painkiller Propofol.
Murray already has a Houston law firm building his defence. Police affidavits say he admitted loading up Jacko, 50, with Propofol and other drugs in the hours before his death.
The prosecution is likely to use lawyer Patrick Dixon, who helped put Phil Spector behind bars.
But on Saturday a Jackson family source said: "We are all keeping our faith with the police. We want them to do this case properly and put away the man who we feel is responsible for Michael's death.
"We want the authorities though to release details of what happened to Michael in his last few hours. We want the paperwork to come out to show just what drugs were put inside him and what happened in his last few hours alive.
"Much of the documentation has been kept secret - and we can't understand it.
"We still feel that there is more than one person responsible for Michael's tragic death. Joe won't give up on getting justice for his son and a lawuit is his focus."
