Police are still not saying what motivated the gunman who walked into a crowded Aurora, Colo., movie theater, shot 12 people dead and injured more than 50. The shooter was well-armed and believed to have acted alone.
Police immediately apprehended the suspect, identified as 24-year-old James Holmes, outside the multiplex. Until recently, Holmes was a student in a graduate program at the University of Colorado, Denver.
