One of CCA's other original (1993) instructors, and one of the Lead ACT and Tactical Training Instructors, Steve Norton, met Steve Emerson as a rookie at the Aurora police department and was struck by the latter’s willingness to help him learn. The two quickly became fast friends and worked together not only at the training academy, but in other capacities. “He was one of those guys who you always trusted,” Norton said. “He was highly skilled and highly competent, but had a kindness and humor about him that was really unique. People were drawn to Steve, as I was, and over the years he became a big brother more than a colleague. He really was a great man. And it really is a great loss. I’m truly saddened by his passing.”
