Martinez, Calif. ? A woman who fatally stabbed her millionaire psychotherapist husband, whom she met as a 14-year-old girl in treatment, was sentenced Friday to 16 years to life in prison for murder.

Susan Polk received the maximum sentence after acting as her own attorney in a trial permeated with theatrics, including discussion of her psychic powers and cross-examination of her own sons. An attorney representing her Friday said she planned to appeal.

The 49-year-old suburban housewife was convicted in June of second-degree murder in the October 2002 killing of Felix Polk, 70, at the couple’s home in Orinda, a wealthy town east of San Francisco.

Polk did not appear surprised by the sentence. Earlier, she told the court she was prepared to go to prison and intended to be productive for however long she was there.

“I won’t be able to bake cookies, but maybe I’ll write a couple of good stories,” she said.

Polk said she killed her husband in self-defense after years of abuse and said authorities fabricated and suppressed evidence in the case.

She testified that she seized a kitchen knife from her husband during an attack near their swimming pool and used it to stab him. But prosecutors said she had no wounds to indicate she was protecting herself and Felix Polk had more than a dozen stab wounds.

Polk said her husband began abusing her while she was his teenage therapy patient, and argued that should be a mitigating factor in her sentencing.
