Voters in Arapahoe, Douglas, Elbert and Lincoln counties chose Republican George Brauchler over Democrat Ethan Feldman on Tuesday.
Brauchler is a prosecutor and former Defense Attorney, who has experience in military law from his Army service.
Brauchler will replace the current DA for the 18th judicial district, Carol Chambers, who was subject to term limits.
With the prosecution of the Aurora theater-shooting suspect James Holmes underway, there was a renewed interest in the race for District Attorney in 18th judicial district. Holmes, a former University of Colorado-Denver graduate student is accused of killing 12 people and wounding 58 others during a July 20 attack at an Aurora movie theater.
9NEWS sat down with Brauchler on Wednesday to ask how he views his job, and what will happen to the Holmes case.
He also talked about his background - including being born and raised in Colorado.
