Officials winnow jury pool in case against Conrad Murray

The first phase of jury selection in the trial of Michael Jackson's doctor concluded Friday with 145 prospective jurors cleared for further questioning after answering an in-depth questionnaire probing their views about the King of Pop and the criminal case against his doctor.

The 30-page questionnaire, which seeks extensive personal information, challenged prospective jurors to share their feelings about the dead superstar and about the fact that his famous family members will be in court every day for testimony.

They were required to specify how much they know about the involuntary manslaughter case against Dr. Conrad Murray, who has pleaded not guilty in Jackson's death from an overdose of the anesthetic propofol.

Murray could face four years in prison and the loss of his medical license if convicted. The trial, expected to last about five weeks, will focus on the cardiologist's actions in the final hours of Jackson's life.
