The Placer County Sheriff's Department had been sent an anonymous letter alleging that the Kubby's had been operating a major grow operation from their residence, and began an investigation. Kubby learned of this, and invited them to inspect the grow room, by passing a note through his own household trash, which the police had begun searching. That note, " ... addressed to law-enforcement personnel, advising them of Steve Kubby's use of medicinal marijuana, maintenance of a garden, possession of no more than 3.5 pounds of pot and his cancer condition," was removed from his trash and entered as evidence by the prosecution.US CA: MMJ: Kubbys Knew Of Impending Arrest
