Meanwhile, Katherine and Joe Jackson did not shy away from the press walking through the main entrance of the court house.
Once inside the courtroom, the Jacksons sat in the front row right behind Murray. The 57-year-old doctor is accused of administering a lethal dose of the antiseptic propofol to Jackson in the bedroom of the singers rented Holmby Hills mansion.
Murray's attorneys have said that the doctor did not give Jackson anything that should have killed him. And his defense teams wants permission to retest three fluid samples currently being held by the coroner's office.
The defense says that the samples were obtained from two syringes and an IV. But, the DA has issues with re-testing and wants to make sure the integrity of the samples is preserved. The judge has urged both sides to work out a deal on the request.
Meanwhile, the date for the preliminary hearing was set for January 4. It is expected to last at least two weeks, and after the judge will decide if there is enough evidence to order the cardiologist to stand trial.
Murray has pleaded not guilty.
