Election workers report receiving suspicious packages, some containing fentanyl, while workers process ballots

Four county elections offices in Washington state were evacuated Wednesday after they received envelopes containing suspicious powders — including two that field-tested positive for fentanyl — while workers were processing ballots from Tuesday's election.

The elections offices were located in King County — home of Seattle — as well as Skagit, Spokane and Pierce counties, the Secretary of State's Office said in emailed news release. Local, state and federal agents were investigating, and no one was injured, officials said.

Renton police detective Robert Onishi confirmed that an envelope received by workers at a King County elections office field-tested positive for fentanyl, while Spokane Police Department spokesperson Julie Humphreys said in a news release that fentanyl was found in an envelope at the Spokane County Elections Office.
