Batman gunman stays silent in court
The man accused of gunning down 12 people at a midnight showing of the new Batman film in Colorado has appeared in court for the first time.
Unshaven and appearing dazed, with his brown hair dyed a shocking shade of orange, James Holmes sat virtually motionless.
It was the world's first glimpse of the 24-year-old since Friday's massacre which also left 58 injured in one of the worst mass shootings in US history.
Holmes did not say a word during the hearing in Centennial, Colorado.
Prosecutors said later they did not know if Holmes was on medication. Authorities have said he is being held in isolation.
His demeanour appeared to anger the relatives of some of the victims who attended the hearing and stared at him the entire time.
Holmes, whom police say was clad in body armour and armed with an assault rifle, a shotgun and handguns during the attack, was refusing to co-operate in the investigation, authorities said. They said it could take months to learn what prompted the attack.
He is expected to be formally charged next Monday. He is being held on suspicion of first-degree murder and he could face additional counts of aggravated assault and weapons violations.
Prosecutor Carol Chambers said her office is considering pursuing the death penalty against Holmes.
She said a decision would be made in consultation with victims' families.
