Sgt. Cowper has served for over 33 years and is still making a difference at work. He recently taught a course for newly promoted sergeants in detention unit procedures and is mentoring new sergeants up until his retirement. While on-duty, he recognized the need to send a prisoner to hospital, which turned out to be a life saving call. The prisoner returned a few days later saying that Sgt. Cowper had saved his life as he had a blood clot that, left untreated, would have likely killed him.

Throughout his career, Sgt. Cowper has served his community by sitting on the Board of Directors for Crossroads, a men's empowerment group, and was also the chef at Windsor Police Camp Brombal for local youth for 10 consecutive years.
