LOS ANGELES (AP) — A judge says he will ask prospective jurors to answer about 160 questions on a 30-page questionnaire in preparation for the involuntary manslaughter trial of Michael Jackson’s doctor Conrad Murray.

The judge set an initial round of questioning for March 24 and 25. Candidates will be ordered back in May to undergo in-person questioning about their lives and views of the case involving the death of the pop superstar.

Superior Court Judge Michael Pastor warned lawyers that he doesn’t want questions made public until the questionnaires reach jury prospects.

He also approved a defense request for access to original fingerprints taken from a broken syringe in Jackson’s bedroom. The lawyers are seeking to show Jackson injected himself with the powerful anesthetic propofol, causing his death.

Murray has pleaded not guilty.
