James Holmes: Mug shot of Aurora, Colorado shooting suspect released

 AURORA, Colo. -- Aurora theater shooting suspect James Holmes appeared despondent and drowsy in court on Monday, his first public appearance after his arrest in a shooting at an Aurora movie theater that killed 12 and injured dozens more.

Holmes' hair had been dyed red and orange. Previous reports indicated after he was arrested, Holmes told police that "he was the Joker." The Joker character has sported different hair colors of the years in the Batman movie series.

Several hours after his appearance in court authorities released Holmes's booking photo.

Monday's hearing at the Arapahoe County Courthouse was to inform Holmes of his constitutional rights.

Holmes, 24, is being held without bond in isolation in the Arapahoe County Detention Center on suspicion of multiple counts of first-degree murder.

During the hearing, Holmes sat quietly and stoically. At times, he appeared wide-eyed, then seconds later, he closed his eyes and lowered his head.

Holmes did not speak and did not enter a plea. A plea is expected to come much later.

Holmes appeared in a burgundy jail shirt and was handcuffed. He sat with a woman who appeared to be an attorney. However, Holmes is expected to be represented by James O'Connor, Arapahoe County's top public defender. Authorities said the case is likely to stay in state court.

The judge scheduled a second hearing for next Monday, July 30. The judge said Holmes will be formally charged at that hearing.
