Police said they had cleared all remaining threats from the booby-trapped apartment of the gunman accused of the Batman theater massacre that left 12 people dead in Colorado. The alleged shooter\'s home was cleared after a lengthy operation and as the names of those who died early Friday were released -- including a six-year-old girl whose mother was also injured and two US servicemen.

The alleged shooter\'s home was cleared after a lengthy operation and as the names of those who died early Friday were released -- including a six-year-old girl whose mother was also injured and two US servicemen. The White House said President Barack Obama would meet with families of the victims and local officials in Aurora, the city near Denver where James Holmes, 24, is said to have opened fire during a packed midnight screening of \"The Dark Knight Rises.\" The actor who plays the caped crusader in the film, the last in the Batman trilogy, voiced sorrow at the shooting, and the studio behind the movie said it was withholding box office data out of respect for the victims. \"Words cannot express the horror that I feel,\" British actor Christian Bale said in a statement. \"I cannot begin to truly understand the pain and grief of the victims and their loved ones, but my heart goes out to them.\" \"We also think it begins to explain some of the materials that he had in his apartment,\" he said. \"What we\'re seeing here is evidence of, I think, some calculation and deliberation.\" Oates flatly declined to speculate on any motive for Holmes, who is due to make his first court appearance on Monday. Out of \"an abundance of caution,\" bomb-sniffing dogs had made a sweep of buildings at the University of Colorado medical school, which Holmes attended until last month, but did not find anything unusual, Oates said. Holmes had no criminal record aside from a citation for speeding in October 2011, according to police. Cinemas in New York tightened security at Batman showings, and the AMC theater chain announced a ban on face masks and fake weapons, while a French premiere was canceled on Friday. Aurora is 20 miles (32 kilometers) from the scene of the 1999 Columbine High School massacre, in which two students shot dead 13 people before committing suicide.
