Meanwhile, the 'Thriller' hitmaker's family have reportedly requested a third autopsy be carried out on the late pop star's body in order to prove foul play.

His mother Katherine is convinced her son was murdered and wants another opinion on the cause of his death.

A source said: 'Katherine looked at the second autopsy and she wasn't happy with what it didn't reveal to her.'

The Los Angeles County coroner's office has not yet ruled on the cause of death, with results currently delayed indefinitely.

Police are currently investigating Conrad Murray on accusations of manslaughter.
