The King County Sheriff’s Office (KCSO) served arrest warrants in Arlington and Bothell, which led to a local drug trafficker being taken into custody, KCSO announced.
Several pounds of narcotics and cash were seized during the arrest, including:
- 11.8 pounds of methamphetamine
- Six pounds of fentanyl powder
- 1.2 pounds of cocaine
- 223.6 grams of heroin

On Nov. 17, KCSO announced that the department successfully executed a major drug bust, seizing nearly 120 pounds of narcotics that had direct ties to the Sinaloa Cartel.
“Operation Eastbound and Down” included a months-long investigation by the Precinct 4 Special Emphasis Team, which uncovered a supplier distributing narcotics across several Washington counties, KCSO announced.
Involved in the drug bust was K9 Quinn, a narcotic K-9 trained to alert to the odors of cocaine, methamphetamine, and heroin. Quinn is currently the only drug dog for the sheriff’s office after Fury retired earlier this year, KCSO confirmed to MyNorthwest.
The supplier would receive more than 100 pounds of drugs every few weeks and later distribute them across King, Pierce, and Snohomish Counties.
Along with KCSO’s K9 Quinn, several search warrants were conducted in Bridgeport, Lynnwood, and Kirkland. Quinn is a former Purina Puppy Chow model who has been on Burien’s police force since November 2022.
“[K9 Quinn] made another great bust that involved this alleged drug ring in multiple counties and multiple cities, and it was a really big bust,” said Casey McNerthney with the King County Prosecutor’s Office.
In total, KCSO seized the following from the search warrants:
- 70.55 pounds of Methamphetamine
- 16 pounds of fentanyl powder
- 6.83 pounds of Heroin
- 1.67 pounds of Cocaine
- One handgun
- One car (Used to distribute narcotics)
- $83,652 cash seized (Drug Proceeds)
KCSO noted the approximate street value of the narcotics seized was $1.3 million.
“This shows how much of this is moving through the region. One way to think of it is if you went to WinCo to the bulk food section and tried to load up 70 pounds of flour, everyone would look at you like, ‘What are you doing?'” McNerthney said.
Officers arrested four suspects tied to the drug-selling operation.
