Michael Jackson - Michael Jackson Self-injection 'Extremely Unlikely'
An expert on anesthetic Propofol has told jurors it is ''extremely unlikely'' Michael Jackson would have caused his own death by swallowing the drug.
An expert on anesthetic Propofol says it is "extremely unlikely" Michael Jackson would have caused his own death by swallowing the drug.
Anesthesiologist Steven Shafer took to the stand today (20.10.11) in the case against the late 'Thriller' hitmaker's personal physician Dr. Conrad Murray, who has been charged with involuntary manslaughter of the pop star after he was accused of giving him an overdose of Propofol while trying to help him sleep.
Coroner's officials have determined the singer died from acute Propofol intoxication and also noted there was anti-anxiety drug lorazepam in Michael's system in June 2009.
Shafer - who is expected to be the prosecution's last witness - told jurors that the drug cannot enter the bloodstream in a sizeable quantity if it is swallowed and said based on Murray's timeline of events, where he says he was away from the pop star for just two minutes, there would not have been sufficient time for Michael to inject himself.
He explained: "The possibility of a direct self-injection seems extremely unlikely."
Shafer reminded the jury that injecting Propofol is a complicated process and showed them various formulas and diagrams on a large screen.
He said the defence's argument that Michael gave himself the powerful anesthetic was also unlikely because he would've been groggy from other drugs administered throughout the night.
He explained: "He can't give himself an injection if he's asleep.
"People don't just wake up from anesthesia hell bent to pick up a syringe and pump it into the IV. It's a crazy scenario."
Shafer said it was more likely that Murray gave the singer a higher dose of Propofol than he told police and he also explained the defence's own testing showed Michael hadn't swallowed any lorazepam pills in the four hours before his death.
Murray's attorneys have previously argued Michael gave himself extra doses of Propofol and lorazepam without the doctor knowing - but the anesthesiologist said those doses would've amounted to just 10 per cent of the drug found in his body at the autopsy based on the timings Murray has given.
He said: "It's only 10 percent of what was measured, so this did not happen.
Prosecutor David Walgren asked Shafer: "The blood levels proved that there is more than four milligrams of lorazepam administered to Michael Jackson?"
And Shafer replied: "Absolutely."
Murray - who denies involuntary manslaughter - could face four years in prison if convicted.
The prosecution is expected to rest later today, with the defence set to call witnesses tomorrow (21.10.11).
