SEATTLE (AP) — Federal agents have made more arrests in a drug pipeline that stretches from Mexico to north of Seattle in Snohomish County.

The Herald reports authorities seized what they believe to be 16,000 fentanyl pills, 30 pounds of methamphetamines and 6 pounds of heroin, according to the U.S. Department of Justice.

Eight people, including five from Snohomish County, were indicted Wednesday in U.S. District Court in Seattle. They are: Jose Luis Ibarra-Valle of Woodinville; Jesus Gutierrez-Garcia of Everett; Jesus Garnica-Melgoza of Seattle; Humberto Garcia of Everett; Santos Caro of Portland, Oregon; Charles Hoffman of Tulalip; Lee Wallette of Mountlake Terrace; and Tisha Girtz of Lake Stevens.

It wasn’t immediately known if the people indicted have lawyers to comment for them.

Most of the drugs were seized from Ibarra-Valle, a Mexican citizen living in Woodinville, who was stopped by law enforcement in Seattle on Oct. 25, according to the Justice Department.

He had 10,000 pills in his car believed to contain fentanyl, more than 20 pounds of suspected methamphetamine and more than 2 pounds of suspected heroin, the Justice Department said. Court-approved searches were done Wednesday after a wiretapping investigation.
