Atherton  

Atherton is in San Mateo County, California, with a population of 7,188. It has the highest per capita income and cost of living in the U.S. among towns of its size.

Land use in Atherton is restricted. There’s no commercial zoning, meaning the town is not cluttered with restaurants, shops, or grocery stores inviting unwanted visitors.  The average home price is more than $7.5 million.

Meet the Seller

Samuel Bronfman II, an heir to the Seagram liquor empire, purchased the mansion 37 years ago for $3.3 million. 

He bought the home 11 years after he was kidnapped in 1975, by Mel Patrick Lynch and Dominic Byrne, and held for $2.3 million ransom, which his father Edgar Bronfman Sr. paid under an aqueduct in Queens.  

While both Lynch and Byrne initially confessed to the kidnapping, they changed their stories, claiming Sam masterminded his own kidnapping to raise cash, and that Lynch and Sam were lovers. The jury acquitted the two men of kidnapping, but found them guilty of extortion.

Sam, who denied his involvement vehemently, lived under this shadow. It may have caused the decimation of the Bronfman fortune. With doubts lingering about Sam, his father bypassed him for running Seagram and named his younger brother as successor. 

Edgar Jr. constructed a merger with the French company Vivendi — giving Vivendi 51 percent in a deal that may have been a little shy in due diligence, since Vivendi was on the verge of bankruptcy. The merger resulted in the Bronfmans losing 75 percent of their fortune.

Sam Bronfman, choosing not to work under his younger brother, became the co-founder of Bacchus Capital Management, a San Francisco-based investment firm. 

Samuel’s younger sisters, Sara and Clare Bronfman, distinguished themselves for their work related to the self-help life coaching group NXIVM. In 2020, Clare Bronfman was sentenced to 81 months in prison due to her NXIVM-related activities. For the same reasons, Sara exited the USA and is living in Portugal.

As for Sam’s role in the kidnapping, one of the kidnappers’ lawyers said in a “deathbed” memoir that Sam was truly kidnapped, and that Lynch and he lied to the jury to get the kidnappers off.

The FBI said they had found no evidence that Bronfman was involved. Representatives of the Bronfman family said Sam was at college in Williamstown, Massachusetts, when he was supposedly meeting with his purported co-conspirators to plan his abduction in New York.

His work has been cited in hundreds of news outlets, like The New York Times, The Daily Mail, VICE News, CBS News, Fox News, New York Post, New York Daily News, Oxygen, Rolling Stone, People Magazine, The Sun, The Times of London, CBS Inside Edition, among many others in all five continents.

His work to expose and take down NXIVM is featured in books like “Captive” by Catherine Oxenberg, “Scarred” by Sarah Edmonson, “The Program” by Toni Natalie, and “NXIVM. La Secta Que Sedujo al Poder en México” by Juan Alberto Vasquez.

Parlato has been prominently featured on HBO’s docuseries “The Vow” and was the lead investigator and coordinating producer for Investigation Discovery’s “The Lost Women of NXIVM.” Parlato was also credited in the Starz docuseries "Seduced" for saving 'slave' women from being branded and escaping the sex-slave cult known as DOS.

Additionally, Parlato’s coverage of the group OneTaste, starting in 2018, helped spark an FBI investigation, which led to indictments of two of its leaders in 2023.

Parlato appeared on the Nancy Grace Show, Beyond the Headlines with Gretchen Carlson, Dr. Oz, American Greed, Dateline NBC, and NBC Nightly News with Lester Holt, where Parlato conducted the first-ever interview with Keith Raniere after his arrest. This was ironic, as many credit Parlato as one of the primary architects of his arrest and the cratering of the cult he founded.
