Advertise | AdChoicesThe source told NBC News that the suspect had dyed his hair red or orange, which isn't typically associated with the green-haired Joker character. The character also doesn't appear in the newest movie, "The Dark Knight Rises," one of the most eagerly awaited films of the year. Holmes also told police that his apartment had been booby-trapped. When investigators arrived, they peered in through a window from a hook-and-ladder truck and discovered numerous bottles containing an unknown liquid, fire officials said. The bottles were connected to wires. "It's nothing I've ever seen before," said Aurora Police Chief Dan Oates, who said the area was evacuated and that police were expected to remain on the scene "for hours or days." Authorities still hadn't entered the apartment late Friday afternoon. They were examining photographs of the scene to figure out how to deal with the materials. -------------------------------------------------------------------------------- Holmes, a graduate student from San Diego who was in the process of withdrawing from the neuroscience program at University of Colorado-Denver medical school, put up no resistance when he was arrested in a parking lot at the theater, police said. He retained legal counsel and wasn't answering investigators' questions, police said. "We are confident he acted alone," Oates said of Holmes, who was scheduled to appear in court Monday morning to face unspecified charges. Authorities refused to speculate on his possible motive. The victims, who were being treated in six hospitals, included a 6-year-old child. A 4-month-old baby also was treated and released. The oldest reported patient was 45. http://imgur.com/c20IZ James Holmes, identified as the suspect in the Colorado shootings, in a photo from the University of Colorado here is his Photo.
