Murray trial: Jackson could not have self injected, says expert

Michael Jackson was so heavily sedated shortly before he died that he could not have self-administered an additional, lethal dose of the sedative propofol, a medical expert has said.

He dismissed the idea the star could have drugged himself, which was an early argument put forward by the defence, as a "crazy scenario".

Dr Steven Shafer was testifying at the involuntary manslaughter trial of the singer's physician, Dr Conrad Murray.

Dr Murray denies the charges.
