A Los Angeles judge has set Jan. 4 as the date for a preliminary hearing into manslaughter charges against Michael Jackson’s physician, Dr. Conrad Murray, according to Reuters. Murray has pleaded not guilty of involuntary manslaughter in connection with Jackson’s death in June 2009. The preliminary hearing will allow a judge to hear details of both the prosecution and defense team’s cases and determine if there is sufficient evidence to move forward with a full-scale trial.
