CENTENNIAL, Colo. - Attorneys for the suspect in the Colorado movie theater shootings said Thursday their client is mentally ill and that they need more time to assess the nature of his illness.
James Holmes' lawyers made the disclosure at a court hearing in suburban Denver where news media organizations asked a judge to unseal documents in the case.
Holmes, a 24-year-old former Ph.D. student at the University of Colorado, Denver, had the familiar, dazed demeanor that he had in previous court appearances.
Holmes is accused of going on a July 20 shooting rampage at a midnight showing of the latest Batman movie in Aurora, killing 12 people and injuring 58 others.
Defense attorney Daniel King made the revelation about Holmes' illness as he argued that the defense needs more information from prosecutors and investigators to assess their client.
"We cannot begin to assess the nature and the depth of Mr. Holmes' mental illness until we receive full disclosure," he said.
King said Holmes sought out university psychiatrist Lynne Fenton for help. A hearing was scheduled for Aug. 16 to establish whether there was a doctor-patient relationship between them.
There were fewer victims and family members in the courtroom Thursday than at earlier hearings. Several spectators appeared mesmerized by the sight of Holmes, unable to take their eyes off him.
Mental illness "doesn't give him the right to do what he did," Chris Townsond, who escaped the shooting unharmed, said after the hearing. "I don't care how mentally damaged he is."
Analysts expect the case to be dominated by arguments over the defendant's sanity, and Thursday's statement by the defense was the strongest confirmation so far that mental illness will be a key issue.
A court document previously revealed that Holmes was seeing the psychiatrist for unknown reasons.
Holmes' public defenders could argue he is not mentally competent to stand trial.
It was the argument used for Jared Loughner, who pleaded guilty this week to a 2011 shooting rampage in Arizona that killed six people and wounded 13 others, including then-Rep. Gabrielle Giffords.
If Holmes goes to trial and is convicted, his attorneys can try to stave off a possible death penalty by arguing he is mentally ill. Prosecutors will decide whether to seek the death penalty in the coming weeks.
The Associated Press and 20 other news organizations also asked Chief District Judge William Sylvester to scale back a gag order that bars the university from releasing details about Holmes.
Sylvester had said in issuing the order that he wanted to protect the county's investigation. But even Aurora officials have cited the gag order in declining to speak about the city's response to the shootings.
Steven D. Zansberg, an attorney representing the news consortium, noted that state law allows judges to issue gag orders barring prosecutors and law enforcement from commenting.
King opposed the news media motion, saying the gag order ensures fairness. Prosecutor Karen Pearson said she had filed her own argument on the issue in court - and that it is sealed.
Sylvester said he would rule on the matter by Monday. He did not say when he would respond to the news media's request to unseal the court documents.
Those documents include the case file, which makes it impossible for observers to understand prosecution and defense arguments on motions that are referenced by number only.
Those types of documents can be an important source of information for the public and can shed light on how police say Holmes prepared for the shooting and rigged his apartment with explosives.
Gregory Moore, editor of The Denver Post, said before the hearing that the news organizations are trying to perform their watchdog role, making sure the investigation is being conducted openly and fairly.
In Colorado, this type of legal battle has been seen before, including the 2003 case of Los Angeles Lakers player Kobe Bryant who faced sexual assault charges in Vail.
It took a news media challenge to unseal an affidavit in which police laid out their case for an arrest. Bryant maintained his innocence, and prosecutors dropped the case in 2005.
