Murray has been at the centre of the probe after he confessed giving the powerful sedative propofol to Jackson hours before his death. The medic and his legal team will purportedly show the video to demonstrate the depth of Jackson's drug habit to claim Murray cannot be held guilty over the tragedy.
"Murray's legal team have quietly but steadily been building a robust defence case," News of the World quoted a legal source as saying. "A key element will be on-camera interviews Michael Jackson gave where he discusses and admits his drug use and others where he appears to be intoxicated."
"In effect, Michael Jackson himself will be the defence's star witness as they set out to prove he was a seasoned and habitual user and knew how to self-administer. The interviews and other evidence aim to show that Jackson had been addicted to prescription drugs for at least 15 years."
"They will try to prove that Jackson was in poor health and therefore the build-up of drugs and the effects of further doses were increased tenfold because of a weakened system. For these reasons, they will say Murray is not culpable and should therefore be found not guilty," the source added.
