Remembering the victims
Holmes is accused of opening fire July 20 in Aurora during a midnight premiere of the latest Batman movie, "The Dark Knight Rises," killing 12 people and injuring 58. Holmes, 24, has been charged with murder and attempted murder and also faces weapons charges.
He is scheduled to be in court at 9 a.m. (11 a.m. ET) Thursday for a motions hearing.
The prosecution and defense argued for many documents in the case to remain sealed -- the former to assure the integrity of the continuing investigation, and the latter to protect Holmes' right to a fair trial. A judge granted the gag order on August 13.
