(CBS/AP) LOS ANGELES - Dr. Conrad Murray, Michael Jackson's personal physician accused of giving Jackson a lethal dose of an anesthetic, returned to court Friday for individual questioning of potential jurors in his involuntary manslaughter trial.

The approximately 145 potential jurors will be narrowed to a dozen. Prosecutors and defense attorneys have been going through the group's responses to what the judge in the case has called "the most complete questionnaire ever."

The questionnaire includes 32 pages of questions about their background, job history, views of Jackson and exposure to media coverage of his 2009 overdose. In an earlier screening this month, every potential juror said they had some knowledge of the case against Murray, reports The Los Angeles Times.

Due to the extremely thorough questionnaire the judge is giving attorneys on both sides half of the normally allotted time to question the potential jurors as a group in court, according to the Times.

Opening statements are scheduled to begin on Tuesday in Los Angeles.

Murray has pleaded not guilty. Authorities contend he gave the singer a lethal dose of anesthetic propofol in the bedroom of the singer's rented mansion on June 25, 2009.
