Police said they found methamphetamine and 10 firearms, two modified with silencers, in an early Wednesday morning SWAT raid in the 2800 block of Lewis River Road in Woodland.
Officers said they arrested an alleged meth dealer who lives on the property, 50-year-old Terry R. Olson, and three other Woodland men. All were taken to the Cowlitz County Jail.
Olson was jailed on suspicion of possessing meth with intent to deliver, operating a drug house, first-degree unlawful possession of three firearms and use of a firearm noise suppressor, according to a bulletin from the Cowlitz-Wahkiakum Narcotics Task Force.
His bail was initially set at $100,000.
The 7 a.m. raid grew from a joint investigation by the Cowlitz-Wahkiakum task force and detectives with the Clark-Skamania Drug Task Force, who obtained a warrant to search the property.
