From the Humboldt County Drug Task Force:

On November 14th, 2022, Humboldt County Drug Task Force Agents served a search warrant at the residence of Joshua Buchanan (age 36) located in the 7000 Block of Berta Road in Eureka. After a multi-week investigation, the HCDTF believed Buchanan was selling fentanyl and was in possession of several firearms.


Upon arriving at Buchanan’s residence, Agents detained an adult female who was accompanied by a young child. After a sweep of the residence, Agents confirmed that Buchanan was not on scene.

HCDTF Agents searched Buchanan’s residence and located a large safe in the kitchen area. The safe contained multiple assault rifles, handguns, non-serialized firearms, one stolen firearm, high-capacity magazines, a suppressor, a large quantity of ammunition, and indicia for Joshua Buchanan. Buchanan is a convicted felon and is prohibited from possessing firearms and ammunition.

Also, in the kitchen area of Buchanan’s residence, Agents located approximately 5 ½ ounces of fentanyl stored in a large plastic bag.

During the search of the residence, HCDTF Agents received information that Buchanan was possibly in the Rio Dell area. The HCDTF reached out to the Rio Dell Police Department and provided a description of Buchanan and his vehicle.

Shortly after, Rio Dell PD was able to locate Buchanan in his vehicle. Rio Dell PD Officers conducted a traffic stop on Buchanan where he was placed under arrest without incident.
