Seattle, Washington – In a major strike against the Sinaloa Cartel Network, the King County Sheriff’s Office (KCSO) Precinct Four Special Emphasis Team successfully executed a high-profile drug bust, seizing a large quantity of narcotics and cash, authorities confirmed.
Dubbed “Operation Eastbound and Down – The Last Chapter,” the operation took place on December 17, according to KCSO.
Massive Drug and Cash Seizure
During the operation, deputies recovered:
- Approximately 214 pounds of methamphetamine
- Around five pounds of heroin
- $89,780 in cash believed to be proceeds from drug sales
Investigators estimate the street value of the seized narcotics at $2 million, marking a significant disruption to cartel operations in the region.
Arrest and Investigation Details
KCSO confirmed that one suspect was arrested in connection with the bust and booked into the Snohomish County Jail.

Officials have not disclosed the specific location of the seizure, citing ongoing investigative considerations, but emphasized that this operation represents a major disruption to organized drug trafficking in King County.
Canine Unit Plays Key Role
The operation also marked the 30th deployment of K9 Quinn this year. The sheriff’s office highlighted the essential role that canine units play in high-stakes drug enforcement operations, particularly in detecting concealed narcotics and assisting deputies in large-scale investigations.
KCSO praised the combined efforts of deputies, K9 teams, and investigative units for the successful removal of drugs and cash from the streets, stressing the department’s ongoing commitment to combatting organized crime.
Impact on Community Safety
The sheriff’s office noted that removing such a large quantity of methamphetamine and heroin from circulation significantly reduces the potential for drug-related violence, overdoses, and community harm.
Authorities also reiterated that dismantling organized drug networks requires coordinated efforts across multiple units, including patrol, investigative, and specialized teams like K9 units.
