Federal, state and local law enforcement partners made 18 arrests and searched more than a dozen locations in connection with a two-year investigation into a violent drug trafficking organization, Acting U.S. Attorney Annette L. Hayes announced Tuesday.

The organization distributed cocaine, heroin and methamphetamine across a wide swath of the greater Seattle metro area, according to a Justice Department press release.

The defendants were scheduled to appear in U.S. District Court in Seattle at 2 Tuesday.

“These defendants preyed on our community by supplying drugs in neighborhoods across Seattle, and demonstrated a willingness to use violence where it served their purposes,” said Acting U.S. Attorney Annette L. Hayes.  “Their criminal activities included hiding weapons and using violence in homeless encampments located along Interstate 5.”

According to the indictment and court records, beginning in February 2013 law enforcement authorities used a variety of tools including telephone wire taps and confidential sources to infiltrate and interdict this drug organization.  The investigation determined that the organization distributed approximately 15-20 kilos of cocaine, 10-15 kilos of heroin and 5 kilos of methamphetamine per month. In addition, on multiple occasions members of the drug trafficking organization were arrested with firearms.  In one instance a conspirator was arrested with a stolen firearm as he was leaving the “Jungle” homeless encampment.  During the investigation law enforcement seized drugs and cash including a September 2014 seizure of two kilograms of cocaine, one pound of methamphetamine and $14,000 cash from a rental car.  In March 2015, investigators seized more than $32,000 from a hidden compartment in another vehicle.

Drug activity associated with the organization occurred over a wide geographic area with drug sales occurring at homes and near businesses in Seattle, Renton, Shoreline and Kent, according to the federal news release.

The drug transactions occurred in areas ranging from the parking lot of Viet Wah supermarket near South Jackson Street, the parking lot of Dick’s Drive-In on Northeast 45th Street, the parking lot of a gas station on Beacon Hill, and at a motel in Tukwila.

“Law enforcement partnerships made today’s operation a success,” said Special Agent in Charge Frank Montoya Jr. of the FBI’s Seattle division.  “Working together in task forces, we tracked these defendants on both sides of Lake Washington, up and down Interstate 5, and even to other states.  Our joint resources enabled us to identify key elements of the organization and effectively shut it down.”
