The man accused of killing 12 people in a shooting at a Batman film screening in Aurora, Colorado in the US has appeared in court for the first time.
James Holmes, 24, sat in court in a red jail suit with dyed orange hair, and appeared sleepy during the proceedings.
Nine of 58 people wounded by the gunman remain in critical condition.
On Sunday, President Barack Obama met survivors and families of the dead as hundreds of people took part in a service of remembrance.
Mr Holmes is to be held without bail at a jail in Centennial, Colorado, the judge said.
Mr Holmes is accused of throwing two canisters of gas into a busy midnight screening of The Dark Knight Rises before firing at random at the crowd. Witnesses say he was wearing full body armour during the attack.
It is reported that a semi-automatic rifle jammed during the attack and the gunman switched to a weapon with less firepower, possibly saving some lives.
Mr Holmes was being held in solitary confinement. Police say he is not co-operating with them.
The dead include a six-year-old girl and two US military servicemen.
Mr Holmes appeared in court at 09:30 local time (15:30 GMT) for the first stage in a process likely to see him face at least 12 counts of first-degree murder. He could face further charges of aggravated assault and weapons violations.
