CENTENNIAL, Colo. — News media organizations were set Thursday to ask the judge in the Colorado theater shooting case to unseal court documents and scale back a gag order that bars a university from releasing details about a former student who is the alleged gunman.

The Associated Press and 20 other news organizations want Chief District Judge William Sylvester to unseal documents that could provide the public with details about James Holmes and the massacre in Aurora on July 20.

The shooting during a midnight showing of the latest Batman movie left 12 people dead and injured 58 others. 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.
