The King County Sheriff Department’s first “bomb dog,” Quincy, has died of natural causes at the age of 12.

The explosives detection dog died Nov. 3, roughly two years after being retired following a 10-year career with the county. He was a black Labrador, trained and certified by the federal Bureau of Alcohol Tobacco and Firearms (ATF). Starting in 1999, he was the only ATF-trained explosives dog in the Pacific Northwest and one of only 18 in the U.S.

Able to detect firearms, gunpowder, shell casings and explosive residue on people, Quincy and his handler, deputy John Decker, were deployed as needed by federal police agencies for events such as the Olympics in Salt Lake City, Utah in 2002. At other times, they helped protect Presidents Carter, Clinton and Bush, among other dignitaries.

Quincy lived with Decker.
