Jackson self-injecting propofol a 'crazy scenario'

US: The claim that Michael Jackson could have self-injected enough propofol to kill himself was a "crazy scenario," the last prosecution witness at the trial of the pop icon's doctor said Thursday.

Anesthesiologist Steven Shafer added that Jackson, who died of acute propofol intoxication, must have had much more of the powerful sedative in his system than the 25 mg which accused doctor Conrad Murray admitted giving him.

Murray's lawyers, who started the five-week manslaughter trial claiming that Jackson could have caused his own death by self-administering propofol, said last week they would no longer claim he could have drunk it. But they have left open the possibility that the star, suffering from chronic insomnia and desperate for rest after a sleepless night, self-injected it via an intravenous (IV) drip in his leg while Murray was out of the room.

"People don't just wake up from anesthesia hell bent to pick up a syringe and pump it into the IV," Shafer said Thursday, adding: "It's a crazy scenario." "Michael Jackson received more than 25 milligrams" of the drug, he added.

Shafer was the last witness for the prosecution in the five-week trial, which began on September 27. AFP
