LOS ANGELES: Prospective members of a jury that will eventually weigh the case against Michael Jackson's doctor are being asked if they had ever seen the King of Pop, attended his concerts, or knew members of his family. A juror questionnaire containing 117 questions was released Thursday after prospects who said they could serve on the two-month trial of Dr. Conrad Murray finished answering. Murray has pleaded not guilty to involuntary manslaughter. He is accused of gross negligence for administering the anesthetic propofol and other sedatives to Jackson before he died. The prospective jury candidates were asked if they had ever seen Jackson or his family members in person, whether they own his records or DVDs, attended his posthumous concert movie, “This is It,” and if so why they watched it. In one section, prospects were asked if they knew any of the more than 100 potential witnesses. The answers of prospective jurors will be released when they are questioned in person beginning May 4. In another twist, lawyers for Murray said in legal documents released Thursday that “gruesome” photos of Jackson's dead body should not be seen in court as they may unfairly sway jurors. In the latest documents, the lawyers argued that jurors seeing the pictures of Jackson's corpse would prejudice the medic's chances of a fair trial.
