Anna Nicole Smith's psychiatrist and boyfriend have been convicted of conspiring to use false names to obtain prescription drugs for the reality TV star.
But the Los Angeles jury acquitted the doctor who prescribed a plethora of drugs for the 39-year-old former Playboy model.
During the nine-week trial prosecutors said the defendants were dazzled by Anna Nicole's glamour and filled her demands for prescription drugs to protect their insider status in her personal life and her celebrity world.
The jury was asked to decide if the three were trying to relieve Anna Nicole's emotional and physical pain or were feeding her addiction to prescription drugs. The model eventually died of an accidental drug overdose in Florida in 2007, but the defendants were not charged in connection with her death.
Dr Sandeep Kapoor said he felt "shellshocked and exhilarated" about being cleared. His lawyer Ellyn Garofalo said it also was a victory in some ways for Anna Nicole. "The jury found she was not an addict," Ms Garofalo said.
The only conviction against Anna Nicole's boyfriend-lawyer Howard Stern was for giving false names and acting by fraud to obtain prescriptions. He was cleared of seven other charges. As he left the court, Stern said the lone conviction came from him trying to protect Anna Nicole's privacy.
Along with conspiracy, psychiatrist Khristine Eroshevich was convicted of unlawfully prescribing Vicodin by fraud. Her lawyer, Brad Brunon, said he would probably move for a new trial and might ask to have the charges against her reduced to misdemeanours.
The defendants had been charged with conspiracy, excessive prescribing of opiates and sedatives to an addict, and fraudulently obtaining drugs by using false names.
