Mystery: The results of the post mortem will not be made public until the police investigation is finished

Michael Jackson's post mortem has been completed - but police are refusing to publish the result until they finish their investigation.
The Los Angeles County Coroner's Office said last night it had now completed its post mortem examination of Jackson's body and related toxicology tests.
But police have asked the office not to release any findings while their investigation is continuing - which could take months.
Ed Winter, assistant chief coroner, declined to comment about when that would be. He said the office would not respond to queries until the police inquiry is finished.
The results are widely expected to show that michael jackson  was on heavy medication when he died at his rented Beverly Hills home on June 25.
The police investigation into Jackson's death has increasingly focused on the role the pop star's personal doctor played in the events leading up to his collapse.
Over the last month, a number of Dr Conrad Murray's offices and his home have been raided by federal agents looking for evidence.
Sources indicate that they are working on the belief that the physician gave the pop star propofol - a powerful sedative - to help him sleep shortly before he died.
Dr Murray has not been named as a suspect but court records have identified him as the subject of a manslaughter investigation.
The news came as a court ruling over the singer's estate gave the green light to a movie based on his final rehearsals.

 

In Los Angeles Superior Court, Judge Mitchell Beckloff approved a deal over the film between the estate of the late singer, concert promoter AEG Live and Columbia Pictures.
Central to the movie will be footage taken as the King of Pop prepared for his sell-out London comeback tour taken just days before he died.

In the week following his death, footage emerged featuring Jackson rehearsing for the shows in Los Angeles. The proposed film would be based on these sessions. It could also include videos prepared for the backdrop of his This is It shows.
Last night's court hearing had been set aside for the judge to rule over the proposed film after Jackson's mother Katherine was given the opportunity to review the contracts and raise any objections.
Mrs Jackson did not object to the film. But her lawyers did raise questions over other contracts concerning AEG Live and merchandiser Bravado. The estate wants to enter into agreement with both firms over the sale of Jackson memorabilia.
Mrs Jackson's lawyer said he had raised several issues over the proposed deals.
In court today Howard Weitzman, a lawyer representing the estate's administrators, said that some of those questions were 'not acceptable'.
He added that the estate had aggressively negotiated the contracts and that there was little room to strike a better deal.
It is also believed that Mrs Jackson wants AEG Live to hand its footage of concert rehearsals to the estate, something it is unwilling to do.
The concert promoter has about 100 hours of footage. Columbia Pictures paid  60 million (£36 million) for the rights to use the images in a film due to be released later this year.
The judge has also appointed a guardian 'ad litem' for the Jackson children.
It means they will have independent representation in court proceedings rather than being represented soley by their grandmother Katherine Jackson.
