Between 28 and 29 August 2017, Lebanon police and the Linn County Interagency Narcotic Enforcement Team executed two related search warrants in Scio and Corvallis in a joint investigation into unlawful butane hash oil manufacturing.[1] Six people were arrested during the raids, which were carried out by the Lebanon police and the Linn County Interagency Narcotic Enforcement Team.[2] Officers arrested George Joseph Nelson, 42, of Scio and Jeremiah Alexander Hart, 42, of Corvallis at the Scio house and booked both into the Linn County jail, while three other people there were detained, cited and released.[2] Police arrested 61-year-old Mark Craig Rose, an emergency-room doctor for Samaritan Health Services, at the Corvallis house, and said there was no indication his alleged activities involved his hospital job.[2] After the arrest Rose was suspended from his emergency-room job pending investigation, and the hospital said he had worked there for 13 years.[3]

Investigators seized one active and one inactive commercial-grade butane hash oil lab across the two searches.[1] Officers found about 6.5 pounds of butane hash oil and about 200 pounds of marijuana, along with ecstasy and user amounts of methamphetamine.[2] Police put the street value of the 6.5 pounds of finished hash oil at about $115,000.[3] The first warrant was served on 28 August 2017 at about 9 a.m. in the 36000 block of Crackerneck Drive in Scio.[1] The second warrant was served on 29 August 2017 at about 1 a.m. in the 2700 block of Marshall Drive in Corvallis.[1]

Police described the Scio setup as a commercial-grade operation that was not licensed or sanctioned by the state to produce hash oil.[3] Investigators said the oil was sold illegally and they were following indications that it was also sold to marijuana dispensaries in the Willamette Valley.[3] The Linn County Regional SWAT Team, Corvallis police, and lab teams from the Oregon State Police and the DEA Eugene office assisted in the investigation and warrant service.[1] Nelson was booked on manufacturing marijuana, delivering marijuana and possessing more than 4 ounces of marijuana, while Hart faced manufacturing and possession counts plus an ecstasy charge and Rose faced two counts each of manufacturing, delivering and possessing marijuana.[2] Rose posted $111,500 bail and was released, with a court date set for 6 September.[3]
