Betty Broderick Dies at 78,The True Crime Icon Behind the Netflix Series Passes Away in Prison obituary

Elisabeth Anne “Betty” Broderick, the woman whose 1989 double-murder case became the subject of the Netflix series Dirty John: The Betty Broderick Story, died on May 8, 2026 at the California Institution for Women in Corona. She was 78. The cause was natural causes.

Who Was Betty Broderick?

On November 5, 1989 — two days before her 42nd birthday — Broderick entered her ex-husband’s home in San Diego and shot Daniel T. Broderick III, a prominent medical malpractice attorney, and his 24-year-old wife Linda Kolkena as they slept. Both died instantly.

The case became a national sensation. To the public, Betty was a devoted mother and former debutante driven to insanity by a bitter divorce. To prosecutors, she was a woman who chose murder over moving on.

Her first trial ended with a hung jury. On December 11, 1991, a second trial convicted her of second-degree murder. On February 7, 1992, she was sentenced to 32 years to life.

Why Her Story Still Matters

Broderick’s case sparked fierce debate about divorce, domestic betrayal, the legal system, and how society treats women pushed to the edge. Decades later, the Netflix dramatization starring Amanda Peet introduced her story to millions of new viewers.

She spent 34 years at CIW Corona, giving occasional interviews where she maintained she was a victim of a system that protected powerful men. She never expressed remorse.
