Betty Broderick, the woman whose explosive divorce and shocking double murder case became one of America’s most infamous true crime stories, has died aged 78 while serving a life sentence in California.
Betty, born Elizabeth Anne Bisceglia, died on Friday, May 8 2026, at an outside medical facility after being transferred from the California Department of Corrections and Rehabilitation prison system for a higher level of care. Authorities said her preliminary cause of death was determined to be natural causes, with an official ruling still pending.

Betty and Dan married in 1969 and raised four children together while Dan built a successful legal career. Friends once described them as the picture-perfect Catholic family, but cracks began to emerge in the early 1980s when Dan became involved with Linda Kolkena, a former flight attendant who later worked as his legal assistant

Betty later claimed she suffered years of emotional manipulation and coercive control during the marriage, while prosecutors argued she became consumed by anger and revenge.
In November 1989, months after Dan married Linda, Betty entered the couple’s home and shot them both while they slept in their bedroom. She was later convicted of two counts of second-degree murder after her first trial ended in a mistrial.

Her appearances on The Oprah Winfrey Show following her conviction only intensified public fascination, as two of her children publicly disagreed over whether she deserved parole.
Over the years, Betty repeatedly argued she had taken responsibility for the killings and should have been released. In a letter written in 2017, she described herself as "a political prisoner" and maintained she had been the victim of long-term domestic abuse.
Prosecutors strongly opposed her release, with San Diego Deputy District Attorney Richard Sachs describing her as "completely unrepentant" during a parole hearing.
Betty remained incarcerated for more than three decades and was next eligible for parole in 2032.
Raised in a strict Catholic household in New York, Betty originally studied English and early childhood education before marrying Dan and devoting herself to family life. Yet decades after the killings, her story continued to spark debate around marriage, infidelity, domestic abuse and the darker side of the American dream.
