Diesel, an 8-year-old Hawaii County police dog, is at the tail end of a career that has detected thousands of dollars in illegal drugs.

The yellow Labrador retriever began his career with a certified narcotics detection team in February 2007 and retires from Kona at the end of the week to live in Waimea.

Diesel’s recoveries include about eight pounds of methamphetamine, 20 pounds of marijuana, two ounces of heroin, three pounds of cocaine, $250,000 in cash seizures and 20 vehicle seizures.

Diesel has "an extremely passive disposition," which allowed him to participate in the DARE program, local parades, educational demonstrations at Hawaii island schools and community events, the Hawaii County police said in a news release.

One of Diesel’s notable recoveries came after police and federal agents received information about a large quantity of methamphetamine being sent from the mainland to Kona. Diesel was deployed to screen luggage at Kona Airport and alerted authorities to a bag that had more than 21⁄2 pounds of meth.

Another time, Hawaii County police investigators used Diesel to check a vehicle driven by a known meth distributor. Diesel found an area where five ounces of methamphetamine were hidden behind the engine and firewall, police said.
