Illegal drugs, prescription pills and guns, including a rifle and shotgun, were seized Thursday as part of a yearlong investigation into drug and firearm trafficking.
About 110 law enforcement officers from 23 federal, state and local agencies in Oregon and Southeast Washington, including the Blue Mountain Enforcement Narcotics Team and Tri-City Metro Drug Task Force, participated in the simultaneous raids on 27 locations, authorities said.
Twenty-nine people were arrested, but their names were not expected to be released until Monday because of the continuing investigation, said Pendleton Police Chief Stuart Roberts.
Roberts also is the board chairman of the Blue Mountain Enforcement Narcotics Team.
The investigation targeted a drug trafficking organization that has been operating in Umatilla, Morrow and Union counties, as well as Southeast Washington and Southern Oregon.
As of Thursday afternoon, officers had seized 6.5 pounds of meth, a half ounce of heroin, almost 800 prescription pills, 23 pounds of processed marijuana and about 200 marijuana plants from four indoor grows, Roberts said.
Eleven handguns, one silencer and 10 long-barrel firearms, including an assault rifle and shotgun, also were recovered, he said.
Locations searched included homes, storage lockers and vehicles. Several suspects with outstanding warrants also were jailed.
