Broderick was serving a life sentence in California over killings and last month transferred to a medical center
Betty Broderick, who became infamous for the 1989 killings of her former husband and his new wife in a case that shocked the country and inspired movies and books, has died at the age of 78 while still serving a life sentence.
Representatives from the California department of corrections and rehabilitation confirmed to NBC News that Elizabeth A Broderick was moved from the California prison where she had been transferred to a medical center on 18 April. She died on the following Friday.
The medical examiner’s office initially determined the cause of death to be natural causes, though the San Bernardino county coroner will carry out a formal investigation, according to NBC.
Broderick became nationally recognized after fatally shooting her ex-husband, Dan Broderick, and his new wife, Linda Kolkena, on 5 November 1989. In 1991 she was found guilty of second-degree murder in connection with their deaths and received a prison sentence of 32 years to life.
