LOS ANGELES (AP) - A jury on Thursday convicted Anna Nicole Smith's psychiatrist and boyfriend of conspiracy in a prescription drug case involving the former Playboy model and reality TV star but acquitted the doctor who prescribed a plethora of drugs for her.

Doctor Sandeep Kapoor was acquitted of all charges.

The only conviction against Smith's boyfriend-lawyer Howard K. Stern was for giving false names and acting by fraud to obtain prescriptions. He was acquitted of other charges.

Along with conspiracy, psychiatrist Khristine Eroshevich was convicted of unlawfully prescribing Vicodin by fraud. The jury deadlocked on several counts against her.

The jury was asked to decide if the three defendants were trying to relieve Smith's emotional and physical pain or were feeding her addiction to prescription drugs.

Smith eventually died of an accidental drug overdose in Florida in 2007, but the defendants were not charged in her death.
