A new video of the suspect in the Colorado theater shooting has surfaced.
In a 2006 video by the Salk Institute for Biological Studies in La Jolla, California, 18-year-old Holmes is seen giving a presentation at a summer camp.
He attended the camp after high school, before attending University of California Riverside.
Salk Institute officials said his presentation centered on temporal illusions, or misfirings in the brain. They described him as a "mediocre" student who was stubborn and didn't take direction.
Holmes is seen occasionally smiling in the video, starkly different from his court appearance earlier this week in which he appeared with bright orange hair and a quizzical look on his face.
Holmes later went on to the University of Colorado Denver neuroscience graduate program.
He is accused of massacring a theater full of people at the new Batman movie in Aurora, Colorado, shooting and killing 12 people and injuring more than 50.
Meanwhile, a judge overseeing the criminal case against Holmes has ordered the University of Colorado Denver not to release his school records.
Numerous media organizations, including The Associated Press, filed open records requests for the records.
But in an order signed Monday and released by the school Thursday in response to an open records request by the AP, District Court Judge William Blair Sylvester said releasing the information would impede the investigation.
