The suspect in last month's Colorado theater shooting was expected in court again Thursday as news media planned to ask a judge to unseal documents and weaken a gag order that keeps a university from releasing details about its former student.

The Associated Press and 20 other news organizations want Chief District Judge William Sylvester to make available documents that could provide details about James Holmes and the July 20 attack at a midnight showing of the latest Batman movie that left 12 people dead and 58 injured.

Holmes, a 24-year-old former Ph.D. student at the University of Colorado, is charged with multiple counts of first-degree murder and attempted first-degree murder.

Arapahoe County prosecutors say releasing documents could jeopardize their investigation. Holmes' attorneys want to ensure he receives a fair trial.

The judge has barred university officials from responding to public records requests concerning Holmes, saying giving out the information would jeopardize the county's investigation.
