NBC's Pete Williams reports the Colorado gunman identified as James Holmes carried two pistols, a rifle, and a shotgun into the midnight showing of "The Dark Knight Rises," and said authorities are looking into how he was able to get in through the theater's emergency exit.
Aurora, Colo., police say they are working on disarming "flammable or explosive material" in the home of James Holmes, the suspected movie theater shooter, and NBC's Pete Williams has more details on the shooter's apartment.
The shooter reportedly never said a word while shooting 71 people and killing 12 in a sold-out show for Batman movie 'The Dark Knight Rises.' NBC's Miguel Almaguer reports.
The honor student, who moved to Colorado last year to study psychiatric disorders, dropped out in June. In recent months, he purchased four weapons and allegedly booby-trapped his apartment with various incendiary and chemical devices. NBC's Mike Taibbi reports.
