Video of Colo. Shooting Suspect Emerges Federal authorities and local police today are scouring James Holmes' apartment for evidence as a newly released video gives some insight into the man who allegedly killed 12 people and injured 58 people at a packed screening of the latest Batman movie, "The Dark Knight Rises." Overnight, ABC News obtained exclusive video and photos of Holmes. The video was recorded six years ago when Holmes was 18. In the video, he is standing among his peers at a science camp at Miramar College in San Diego talking about "temporal illusions." Over the course of the summer I've been working with a temporal illusion. It's an illusion that allows you to change the past," Holmes said in the video. He appears slightly nervous speaking to the group but also extremely intelligent. This is how he was explaining his mentor's shared interest in fantasy versus reality in the video: He also studies subjective experience which is what takes places inside the mind as opposed to the external world. I've carried on his work in dealing with subjective experience. By most accounts, Holmes lived the life of a normal teen â with a particular interest in science. This was how he was introduced at the seminar: "His goals are to become a researcher and to make scientific discoveries. In personal life, he enjoys playing soccer and strategy games and his dream is to own a slurpee machine. Officials Saturday said they now have "evidence of calculation and deliberation," in the way he allegedly planned and prepared for the shooting, beginning to buy weapons and ammunition two months ago. Holmes, 24, is currently in custody for Friday's massacre in Aurora, Colo. Among the dead include: Micayla Medek, 23; Alex Sullivan, 27, who was attending the movie for his birthday; Ohio native Matt McQuinn; Alex Teves, 24; Alexander J. Boik, 18; Rebecca Ann Wingo, 32; and Gordon W. Cowden, 51. John Larimer, a member of the Navy, was also confirmed by his family to be among the dead. The family said they were notified at their Illinois home around midnight today by a Navy notification team that Larimer was dead. Staff Sgt. Jesse Childress was an Air Force reservist assigned to units at Buckley Air Force Base in Colorado was killed in the shooting. Air Force Lt. Col. Pat Walsh said that Childress was respected in the 310th Force Support Squadron. Military veteran Jonathan T. Blunk of Aurora, Colo., was killed as he threw himself over a friend to keep her from getting shot. The 26-year-old worked at a hardware store. Veronica Moser-Sullivan, 6, was killed, according to The Associated Press. The girl's mother, Ashley Moser, 25, is in critical condition after she was shot in the throat and abdomen, said her aunt, Annie Dalton. Aurora Police Chief Daniel Oates announced Friday that Holmes had purchased four guns at local shops and more than 6,000 rounds of ammunition on the Internet in the past 60 days. Inside James Holmes' Apartment Overnight, new pictures have emerged of several explosions in a Colorado field where investigators took chemical materials recovered from Holmes' apartment. Crews reportedly transported the materials by dump truck to the field so that they could be ignited -- and determined if they were in fact explosives. Federal authorities and local police have now pulled all of the potential explosives from Holmes' apartment after gaining entry and eliminating potentially explosive traps Saturday. The apartment, about 800 square feet contained several trip wires rigged to trigger explosions. Scattered throughout the living room were 30 explosive devices - including jars with chemicals and 30 shells with explosive powder - similar to large fireworks. Bomb squads carefully neutralized the two main threats at the entrance of his apartment using a "water shot" and remote-controlled robot. Oates said the suspect's intentions were clear. "What we're seeing here is some evidence of calculation and deliberation," Oates said. Holmes was an honors student and Ph.D. candidate at the University of Colorado Anschutz Medical Campus. He was enrolled in the graduate program in neuroscience until he voluntarily withdrew from the program in June. He was one of six recipients of a Neuroscience Training Grant from the National Institutes of Health, which funds pre-thesis Ph.D. students in the neuroscience program at the Anschutz Medical Campus.
