Sgt. Cooper, Unix demonstrate canine police work

Sheriff's Sgt. Keith Cooper and Unix, an eight-year-old German Shepherd, demonstrate their drug seeking techniques for children at the Whitman County Library in Colfax April 19. Cooper and Unix attended 16-week training in Shelton before working together since 2011. Unix is trained to go to the source. His sense of smell creates a cone and he triangulates the source. Sgt. Cooper said they train every week and train eight hours once a month to conduct searches of homes or vehicles. Unix will be adopted out when he retires after two more years of service.
