In September, a judge ruled that a notebook Holmes allegedly mailed to Fenton right before the shooting would not be accessible to prosecutors.
The judge overseeing Holmes's case agreed last week to delay an arraignment in the case to allow defense lawyers more time to examine more than 30,000 pages of evidence and hundreds of DVDs and CDs.
The arraignment -- a formal reading of charges by the court and, frequently, the entering of a plea by the defendant -- is now scheduled for March 12.
Nearly six months after the killings, the Aurora Century 16 movie theater where the massacre took place will hold a private "night of remembrance" Thursday for the victims and those who responded to the tragedy. The theater will permanently reopen later this month.
Some survivors and loved ones of those killed are boycotting Thursday's event, deeming it as insensitive, while others say it's important that the theater reopen.
Several victims' families and survivors have filed lawsuits against Cinemark USA, Inc., the company that owns the theater.
