A judge on Thursday denied prosecutors’ request to obtain a notebook that allegedly contains a violent description of the shooting that killed 12 and injured 58. Prosecutors said the suspected shooter, James Holmes, mailed the notebook to his psychiatrists, prompting Judge William B. Sylvester to rule that it could be inadmissible due to doctor-patient confidentiality. His final ruling on the matter is expected on Sept. 20. Holmes, 24, a doctoral student at the University of Colorado, has been accused of a shooting rampage during a midnight screening of The Dark Knight Rises. Defense attorneys are trying to argue that Holmes is insane.
