(CBS/KCBS/AP) LOS ANGELES - A judge is expected to hear pre-trial motions Monday in the trial of Dr. Conrad Murray, Michael Jackson's personal physician who is accused of involuntary manslaughter in the June 2009 death of the pop star.Prosecutors want the jury to hear evidence that the Los Angeles Police Department and the L.A. County Coroner's office tried to reach Murray on four separate occasions, but he never returned their calls, reports CBS station KCBS.
A jury of seven men and five women were selected out of 84 prospective jurors for the trial, which is expected to begin Tuesday.
Murray has pleaded not guilty to involuntary manslaughter. His lawyers have said Jackson was contemplating calling off his ten-concert tour, "This is It," if he couldn't sleep. Murray told police he was giving Jackson the anesthetic propofol as a sleeping aid.
The prosecution claims Murray , a Houston cardiologist, was grossly negligent in administering the drug at home without the proper equipment, and then left the room long enough to find his patient not breathing when he returned.
Murray's defense claims the singer, desperate for sleep, swallowed an additional dose of the drug when the doctor was out of the room.
The defense's theory is based on evidence that a trace amount of propofol - .13 milligrams - was found in Jackson's stomach. The drug is administered intravenously, usually during surgery. Scientific witnesses may be asked to explain how it could have gotten into Jackson's stomach. Some doctors say ingesting it orally is almost unheard of.
The prosecution has a key expert witness, as well as forensic experts from the Los Angeles County coroner's office who are considered at the top of the field.
The defense boasts an advantage in one of its lawyers, J. Michael Flanagan, who says he is the only California attorney ever to try a propofol death case.
Murray, who had been consulted by Jackson in his Las Vegas office, was promised $150,000 a month when he signed on as Jackson's personal physician six weeks before he died. He closed the doors of his offices there and in Houston to devote himself to the singer.
Murray said he had been giving Jackson drugs known as benzodiazephines to help with his insomnia, but when they didn't work Jackson demanded propofol.
The physician told police he was trying to wean Jackson off the drug and gave him a minimal dose, then left the room for five minutes to use the bathroom. However, cell phone records suggest he was making phone calls for a longer time. His actions after he found Jackson not breathing are also central to the case.
Jackson died of a propofol overdose in June 2009 at his rented mansion in Holmby Hills, an affluent neighborhood in West Los Angeles.
