Betty Broderick: The Socialite Who Killed Her Ex-Husband and His New Wife in Their Bed
She put him through medical school, raised four kids, and lost everything in the divorce — then she picked up a gun
Key Facts
What Happened
Betty and Daniel Broderick married on April 12, 1969, and for 16 years Betty was the archetypal supportive wife. She worked multiple jobs to put Dan through both Cornell Medical School and Harvard Law School, bore nine pregnancies (resulting in four surviving children — Kim, Lee, Daniel Jr., and Rhett), and managed the household while Dan built what would become one of San Diego's most successful malpractice law practices. By the mid-1980s, Dan was earning over $1 million a year. Then he hired 21-year-old Linda Kolkena as his legal assistant, and the marriage began to unravel.
Dan moved out in February 1985 and filed for divorce. What followed was a years-long legal war in which Dan — a top trial attorney who knew every judge in San Diego — systematically used the court system against Betty. He was awarded sole custody of all four children, had Betty's spousal support reduced, obtained multiple restraining orders against her, and had her jailed for contempt of court on several occasions. Betty became increasingly erratic: she drove her car through Dan's front door, left obscene messages on his answering machine, and vandalized his property. Dan and Linda married on April 22, 1989.
On November 5, 1989 — two days before Betty's 42nd birthday — she took a key from her daughter Kim, entered Dan and Linda's home at 5:30 a.m., and emptied a five-chamber .38-caliber Smith & Wesson revolver into their bedroom. Linda was killed instantly. Dan died within minutes. Betty then unplugged the phone and left. She later turned herself in.
Her first trial ended in a hung jury. At her second trial in December 1991, she was convicted of two counts of second-degree murder and sentenced to two consecutive terms of 15 years to life plus two years for illegal firearm use — the maximum sentence of 32 years to life. She remains incarcerated at the California Institution for Women. Her case was dramatized in Netflix's 'Dirty John' Season 2 and remains one of the most debated divorce-rage cases in American history. She has been denied parole multiple times.
Legal Breakdown: When Divorce Turns Deadly
When the Legal System Becomes a Weapon
Dan Broderick was a top malpractice attorney who knew every family court judge in San Diego personally. He used his legal expertise and connections to obtain sole custody, reduce Betty's support payments, and have her repeatedly jailed for contempt. This case is a textbook example of how a legally sophisticated spouse can weaponize the court system. If you suspect your spouse is manipulating legal proceedings, seek independent counsel who practices outside your spouse's professional circle.
Recognizing Escalating Rage in Divorce
Betty's behavior escalated over four years: from angry phone messages, to driving her car through Dan's front door, to vandalizing his property, to murder. Each escalation was a warning sign that went unaddressed. Mental health intervention, anger management, and therapeutic support during high-conflict divorces are not optional luxuries — they can be life-saving necessities for all parties involved.
The Myth of 'Snapping'
Betty Broderick did not 'snap.' Her rage built over years of perceived injustice, loss of identity, and a legal system she felt was stacked against her. Studies show that most intimate partner homicides are preceded by a long escalation pattern. If you or someone you know is experiencing overwhelming anger during divorce, contact a mental health professional immediately. The National Domestic Violence Hotline (1-800-799-7233) provides confidential support.
