DENVER (AP) — A hearing scheduled in the Colorado shooting case has been postponed a week.

Judge William Sylvester Wednesday approved a request by prosecutors for more time. In documents, prosecutors say they don’t have all the necessary evidence to prepare for the hearing in which they were to argue about access to a notebook sent to a University of Colorado psychiatrist.

Prosecutors say this week they received 2,500 pages of evidence, along with 52 DVDs and CDs and are awaiting more information.

Prosecutors say they should be able to examine the notebook’s contents as part of their investigation into the July 20 shootings in Aurora that left 12 people dead and 58 wounded. Defense attorneys claim Holmes is mentally ill and the notebook is protected by doctor-patient privilege.
