'Dark Knight Rises' Shooting: 'We Will Convict' James Holmes, Aurora Police Chief Says
Daniel Oates also reveals to "Dateline" that his own daughter was watching a screening of the movie at another local theater at the time the shooting occurred.
The Aurora, Colo., police chief said he is confident there will be a conviction of James Holmes, the alleged shooter who killed 12 people and injured dozens of others at a movie theater during a midnight showing of The Dark Knight Rises.
"We will convict him," Daniel Oates told NBC News' Dateline in his first network primetime interview, which aired Sunday night.
On Friday, the 24-year-old allegedly opened fire at the Century 16 movie theater in Aurora, killing at least 12 people ranging in age from 6 years old to 51, and injuring some 58 others.
Oates told Dateline's Kate Snow that the police who arrived on the scene spotted Holmes pretty quickly; he was dress in black body armor.
"These guys were sharp enough to see that the outfit wasn't quite right and they immediately challenged him," Oates said. "I'm just so proud of them for what they were able to identify. And he surrendered immediately."
Oates declined to reveal what Holmes told the police, but "based on what he told us, we were concerned about his apartment."
The apartment, in fact, was booby-trapped. Had the bomb gone off in Holmes' place, the police would have been dealing with "two simultaneous crises at once."
"I have been told by the bomb experts that had someone opened that door it would have triggered that device," Oates said. "It would almost certainly have killed or severely injured whoever opened the door. And would have started, you know, a very big fire that would have been a real challenge for our fire department."
Oates also reveals that his own daughter was watching a midnight screening of The Dark Knight Rises at another Aurora movie theater.
"And I've talked to quite a few friends who have said the same thing about their children," he said.
Holmes is set for an initial hearing at 9:30 a.m. Monday at the Arapahoe County Courts.
More of the interview with Oates will air Monday on NBC's Today.
