Betty Broderick and the Murder of Her Ex-Husband: A Toxic Divorce That Ended in Gunfire
Betty Broderick’s case remains one of America’s most infamous examples of a divorce that spiraled into deadly violence. After a bitter separation and custody battle, she shot and killed her ex-husband Dan Broderick and his new wife Linda Kolkena on November 5, 1989 . This article examines the marriage, the toxic divorce, and the murders that shocked the nation.
1. The Marriage: From College Sweethearts to Millionaire Couple
Betty Broderick (born Elisabeth Anne Bisceglia in 1947) married Dan Broderick in 1969 . She supported her husband through Harvard Law School by teaching and babysitting, while he went on to become a highly successful medical malpractice attorney .
By the 1980s, the couple lived a life of wealth and privilege: a big house in San Diego, a yacht, luxury cars, and a country club membership . But behind the scenes, the marriage was crumbling.
2. The Affair: The Beginning of the End
In 1983, Dan promoted Linda Kolkena—a 22-year-old former flight attendant with no legal training—to be his personal assistant . Betty immediately suspected an affair and gave her husband an ultimatum: fire Linda by October 1 or leave. Dan ignored the threat .
As Betty suspected, Dan and Linda were having an affair. The couple began attending events together, and the office knew about the relationship . In 1985, Dan finally admitted the truth and moved out. He filed for divorce in 1985, and the couple finalized their divorce in 1989 .
3. The Divorce: A Bitter and Public Battle
The divorce was one of the most contentious in San Diego history . Betty felt that Dan used his money and legal power to “beat” her . Dan gained custody of the children, withheld support payments, and sold the family home without Betty receiving a share .
Betty retaliated with acts of vandalism: she drove her car into Dan’s front door, smashed a Boston cream pie made by Linda over their bed, and left obscene messages on their answering machine . Dan obtained a restraining order, and Betty was arrested for contempt of court .
4. The Murders: November 5, 1989
On the morning of November 5, 1989, Betty Broderick used her daughter’s key to enter Dan and Linda’s home . She crept into their bedroom while they slept, carrying a .38-caliber revolver .
She fired five shots: two hit Linda, one hit Dan. Linda died instantly; Dan died soon after . According to reports, Dan’s final words were: “Okay, you shot me. I’m dead” . Betty fled the scene but turned herself in to police later that day .
5. The Trial and Sentence
Betty’s first trial in 1990 ended in a hung jury . A second trial in 1991 convicted her of two counts of second-degree murder . She was sentenced to 32 years to life in prison .
The case sparked intense media attention and public debate. Some viewed Betty as a victim of emotional abuse and financial manipulation, while others saw her as a cold-blooded killer .
6. The Legacy
Betty Broderick died in prison on May 8, 2026, at the age of 78 . She had been denied parole multiple times—most recently in 2010 and 2017—and was next eligible in 2032 .
Her story has been adapted into numerous films and TV shows, most notably the Netflix series Dirty John: The Betty Broderick Story (2020), starring Amanda Peet and Christian Slater . The case continues to serve as a cautionary tale about the dangers of unchecked rage and the devastating consequences of domestic conflict.
