Prominent Socialite Betty Broderick, Notorious for the Murder of Her Ex-Husband, Passes Away

Betty Broderick, a notorious figure known for the murder of her ex-husband and his new wife, has passed away at 78 while serving time in prison.

Broderick’s death occurred on Friday within a California correctional facility, as confirmed by the state Department of Corrections to the Daily Mail.

In the weeks leading up to her death, she had been relocated to a medical center for enhanced care. However, the specific health issues she faced were not disclosed due to privacy regulations.

Authorities have indicated that her death was due to natural causes, with the precise cause to be determined following an autopsy.

Back in November 1989, Broderick was convicted for fatally shooting her former husband, Dan Broderick, and his wife, Linda Kolkena, while they slept.

Dan had an affair with Kolkena in the 1980s after having four children with Broderick. 

Dan and Broderick filed for divorce in 1985 after 19 years of marriage. He married Kolkena, a flight attendant, in 1989. 

Kolkena had been hired by Dan as a legal assistant to help with his marital woes with his wife. He denied the affair until they got divorced.

Broderick fell into a depression during her and her husband’s divorce proceedings 

The former couple fought hard in their divorce over the custody of their children, which Dan was eventually granted. They also battled over who kept their family home. 

The proceedings caused Broderick to fall into a depression and she later killed the new couple. 

She was convicted of two counts of second-degree murder in 1991 and sentenced to 15 years to life in prison. 

Broderick attempted to get parole several times while in prison, but was denied. 

In 2017, she was described as ‘defiant’ and ‘completely unrepentant’ by the San Diego County Deputy District Attorney Richard Sachs. 

Broderick wrote in a letter of a podcast that she was a ‘political prison’ and that the murders were due to domestic abuse.  

The Daily Mail has reached out to the Department of Corrections for comment. 

In 2020, the Daily Mail revealed secret letters written by Broderick to her boyfriend, where she was begging for money and affection.

She shot her husband and his wife in their bed in 1989 

Betty’s boyfriend, Bradley Wright, she began dating before committing murder and he was the one who discovered the bodies of her victims. 

The letters were dated from 2003 to 2006, and they shed a light on Broderick’s time in prison and her turbulent relationship with Bradley, who stayed in touch with his murderous girlfriend and sent her money well after her sentencing in 1991.

The secret stash of love letters were unearthed in a storage unit in San Diego, California, in October 2020 along with checks Bradley sent to Broderick’s daughter and money order receipts.

She gushed over her lover in the correspondence.

In one letter, from April 2006, she wrote: ‘If I had a penny for every time I think of you, I’d be a millionaire many times over.’

The mother-of-four insisted that Bradley was her perfect man in another message.

‘I was thinking of what I’m looking for in a man – since you are not available – well the list was a description of you! You’re exactly the guy! Da**it.’

She also urged Bradley to leave his partner for her and encouraged him to ‘sneak’ away and visit her in prison.

In 2020, the Daily Mail revealed secret letters between Broderick and her lover 

He had sent her money and photographs 

‘If you want to live in [unclear] with me, like you say you do, going back to Lisa is not how that’s gonna happen.

‘I can’t believe you don’t come here! It’s been years! Now that she’s back to work, maybe you can sneak away?’

A photograph of a bride and groom was discovered with the secret stash of letters, implying that Bradley had moved on and married another woman despite the contact with his killer ex behind bars.

Betty even took it upon herself to dispense relationship advice to Bradley and asked him to seek professional help in her letters from prison.

‘Sorry to hear your life is a mess. I don’t want to come back to a mess,’ she wrote.

‘Did you go to counseling? Whatever patterns you have will continue for better or worse.

‘You know the definition of insanity? Doing the same thing over and over and expecting a different result. I should know!’

The couple married in 1969 and Dan went on to graduate from Cornell medical school and Harvard law school to establish a successful medical-malpractice law firm.

Broderick found out about her husband’s affair while visiting his office on his birthday, only to be told he and Kolkena had gone out for the day 

However, as Dan chased his star career, Broderick grew resentful that he neglected her and their children.

Over the years their marriage crumbled, and by 1983, Broderick accused Dan of having an affair with Kolkena, who some claimed looked like the younger version of her.

On one occasion Broderick visited her husband’s office on his birthday and found the remnants of a party.

But her husband was nowhere to be found. A receptionist told her Dan and Kolkena had gone out for the day. Outraged, Broderick went home and burned her husband’s clothes in a bonfire.

Dan later admitted to her that her suspicions were right, that he had been having an affair with Linda for the past two years.

In 1985, Dan filed for divorce. And in 1989, he married Kolkena, but the tensions between the newlywed couple and Broderick only intensified.

Broderick went on a rampage, including defacing the couple’s former home, ramming her car into his front door and leaving obscene messages on his answering machine.

She also repeatedly told their children that she would kill him.

In return, Dan had Broderick arrested and placed in a mental facility, as well as obtaining a restraining order against her, and barring her from entering his property, which she repeatedly ignored.

Seven months after Dan’s remarriage, Broderick broke into Dan and Kolkena’s home on November 5, 1989, at around 5am and shot them both dead.
