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 lawyer in a trial permeated with theatrics, including discussion of her psychic powers and cross-examination of her own sons.

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.
