Federal agents and local police executed 13 search warrants on indoor marijuana grow operations across King County early on 10 September 2008 as part of Operation Green Reaper.[1][2] The DEA said the raids targeted command-and-control elements of Puget Sound indoor grow organisations.[1]

Plants, cash and arrests

Law enforcement seized 4,578 marijuana plants, three weapons including an assault rifle and a shotgun, about US$50,000 in cash and 20 vehicles, and took 20 people into custody.[1][2] Kent Police Chief Steve Strachan said the case reflected a large-scale criminal enterprise rather than small-scale cultivation.[2]

Assistant Special Agent in Charge David Dongilli warned that growers were modifying suburban homes with unsafe wiring, irrigation and chemicals that could contaminate sewers and leave houses uninhabitable.[1][2] Agencies involved included the DEA, Kent, Auburn, Renton, Tukwila and Port of Seattle police, with support from the Washington State Patrol, Seattle Police, King County Sheriff’s Office and others.[1][2]
