'The nose knows:' Police K-9 Mark out-sniffs the competition, crime

At a command from Auburn Police K-9 Officer Luis Coreano, narcotics detection dog Mark runs through the abandoned building from room to room, nose inhaling furiously. Entering the closet where a small pouch of powdered cocaine is hidden inside a boot for the training exercise, the nearly 8-year-old Belgian Malinois slows his pace and sniffs more carefully around the area. As his nose passes over the boot, Mark suddenly sits and snaps his head around to look at Coreano, alerting his handler to the narcotic’s presence.
