Betty Broderick

Elisabeth Anne Broderick ( Bisceglia; November 7, 1947 – May 8, 2026) was an American woman who murdered her ex-husband, Daniel T. Broderick III and his succeeding wife, Linda, on November 5, 1989, as an act of revenge after Daniel cheated on and divorced her. At a second trial that began on December 11, 1991, she was convicted of two counts of second-degree murder and later sentenced to 32 years to life in prison.

Early life Betty Broderick was born Elisabeth Anne Bisceglia, on November 7, 1947, and grew up in Bronxville, New York. and Frank Bisceglia (1915–1998), who owned a successful plastering business with relatives. Her mother was Irish American and her father was Italian American.

The Bisceglias were strict parents and much was expected of all the Bisceglia children. As Broderick later recalled, she was being trained to be a housewife since the day she was born, or as she recalled: "Go to Catholic schools, be careful with dating until you find a Catholic man, support him while he works, be blessed in your later years with beautiful grandchildren." She recalled that her school friends were raised under similar circumstances, giving her little chance to rebel.

Broderick attended Maria Regina High School, in Hartsdale, New York, and graduated from Eastchester High School, in Eastchester, New York, in 1965. She graduated from the College of Mount Saint Vincent, in the Bronx, where she earned a degree in early childhood education through an accelerated program. Her credits also earned her a minor in English.

Engagement and marriage In 1965, Elisabeth (Betty) met her future husband, Dan Broderick (1944–1989), at the University of Notre Dame in Indiana. Dan was born in Pittsburgh, Pennsylvania, the eldest son of a very large Irish Catholic family, whose parents had a similar outlook as the Bisceglias. Dan and Betty met at a dance at Notre Dame. He was a 21-year-old senior about to graduate and attend Cornell Medical School.

At 17 years old, she was pursuing her degree at the College of St. Mary's. "Dan never once wavered from his goal of making me his wife. He would wait, he would do and say whatever was necessary, even agreeing with me when he didn't, and doing things I wanted to do when he didn't, until he had me. Nobody ever used the terms 'obsessive-compulsive' or 'stalker' back then, but that is what he was."

The couple married on April 12, 1969, at the Immaculate Conception Church in Tuckahoe, New York. Betty returned from the honeymoon pregnant with their first child, daughter Kim (born 1970). She gave birth to four more children: daughter Lee (born 1971), sons Daniel (b. 1976) and Rhett (born 1979), and an unnamed boy who died four days after birth.

Marriage breakdown After Kim's birth, Dan completed his M.D. degree at Cornell in 1970. He then announced his intention to combine his medical expertise with a J.D. degree and enrolled at Harvard Law School. Betty was the main provider for the family while Dan attended law school with the help of a student loan. After graduating in 1973, Dan was quickly hired by the largest law firm in San Diego, California, which had a substantial defense litigation practice, and moved his family to the San Diego community of La Jolla.

Betty continued working part-time, often selling Tupperware or Avon products, while raising the children. In 1978, after five years of substantial defense litigation work and training as an associate, Dan left the large firm where he was well regarded. He then founded his own small boutique law firm, specializing in medical malpractice litigation on behalf of plaintiffs. Because of Dan's background as both an M.D. and trial attorney, the firm quickly enjoyed success.

In the fall of 1982, Dan hired 21-year-old Linda Kolkena (1961–1989) as his legal assistant at his new firm. As early as October 1983, Betty suspected that Dan was having an affair with Linda, but Dan denied it. Against Betty's wishes, Dan moved out in February 1985. Betty also believed that Dan used his legal influence to win sole custody of their children, sell their house against her wishes, and cheat her out of her rightful share of his income. The divorce was finalized in 1989, four years after Dan filed the petition.

Betty Broderick's behavior became increasingly erratic. She left hundreds of profane messages on Dan's answering machine and ignored numerous restraining orders that forbade her from setting foot on Dan's property. She vandalized his new home and even drove her car into his front door, despite the fact that their children were inside the house at the time.

On April 22, 1989, Dan and Linda were married. Linda had been concerned about Betty's behavior and even urged Dan to wear a bulletproof vest at their wedding. Dan refused to do so, although plain-clothes security was employed. However, Betty did not attend the wedding and it proceeded without incident.

Murders One month before Dan and Linda's wedding, Betty purchased a Smith & Wesson revolver. Early one morning, seven months after Dan and Linda were married, Betty Broderick drove to Dan's house at 1041 Cypress Avenue in the Marston Hills neighborhood, near Balboa Park in San Diego.

Trials and imprisonment Criminal defense attorney Jack Early represented Broderick at trial. Kerry Wells prosecuted for the State of California. Broderick's defense claimed that she was a battered wife driven over the edge by years of psychological, physical, and mental abuse inflicted by her ex-husband. Wells portrayed Broderick as a murderer who planned and schemed to kill her ex-husband, arguing that Broderick was not a battered woman.

Forensic psychiatrist and criminologist Dr. Park Dietz, for the prosecution, used the analysis of Dr. Melvin Goldzband, who previously worked on the case for the prosecution. Dietz said Broderick had histrionic and narcissistic personality disorders. Goldzband diagnosed Broderick as "severely narcissistic" and "histrionic". Clinical psychologist Katherine DiFrancesca, testifying for the defense, concluded Broderick was "histrionic" with "narcissistic features".

The lead detective in the case was Terry DeGelder of San Diego Homicide, who provided testimony for the prosecution.

Broderick's first trial ended with a hung jury when two of the jurors held out for manslaughter, citing lack of intent. A mistrial was declared by Judge Thomas J. Whelan. Betty Broderick was re-tried a year later with the same defense attorney and prosecutor. The second trial was, essentially, a redux of the first. Prosecutor Wells was successful at the second trial. The jury returned a verdict of guilty on two counts of second-degree murder.

Broderick was sentenced to two consecutive terms of 15 years to life, the maximum sentence under the law, plus two years for the illegal use of a firearm. She was incarcerated from the day she committed the murders until her death.

At the time of her death, Broderick was serving her sentence at the California Institution for Women (CIW) in Chino, California. In January 2010, her first request for parole was denied by the Board of Parole Hearings because she neither showed remorse nor acknowledged wrongdoing. She was again denied parole in January 2017. She would not have been eligible for parole again until January 2032, when she would have been 84 years old.
