Mysterious FOURTH Alexander Brother Unmasked: All the Family Scandals of Israeli Billionaire Heiress Wife… As He Cuts Lonely Figure at Siblings’ Sex Crimes Trial
By LUKE KENTON, US SENIOR REPORTER
The story of the Alexander brothers is best known as a tale of three high-flying siblings accused of abusing their wealth and power to drug and rape women.
A saga of private jets, penthouses and unchecked excess now unraveling under the glare of a federal sex-trafficking trial, where they have all pled not guilty.
But there is a lesser-known fourth brother – the eldest – raised in the same North Miami home as Tal, 39, and twins Alon and Oren, 38, whose life has followed a markedly different path, albeit one still defined by extraordinary wealth and opulence.
Niv Alexander, 45, has appeared several times at the Manhattan federal courthouse, offering what has so far been quiet solidarity with his brothers who face life in prison if convicted of the most serious crimes.
He maintains a low profile and sits away from the rest of the family, making notes on a large notepad. Niv has not been accused of wrongdoing and is not charged in the case.
At his side during a late-January appearance was his wife, Cassie Arison, a philanthropist and heiress to the Carnival Cruise empire whose family has had their own fair share of scandal.
Her mother, Shari Arison, is widely considered Israel’s richest woman, with an estimated net worth exceeding $5 billion.
In contrast to the nightlife notoriety and headline-grabbing success that once defined his younger brothers’ public personas, Niv has largely kept a lower profile.

On LinkedIn, he describes himself simply – and vaguely – as a ‘contrarian investor type.’
He serves on the board of the Jerusalem Foundation and previously worked as a journalist for Yedioth Ahronoth, one of Israel’s largest daily newspapers.
For eight years, he worked at the private security company founded by his parents, Shlomi and Orly Alexander, in Miami – the enterprise that propelled the family into affluence.
Unlike his younger siblings, Niv’s public record is relatively sparse. Florida court filings show a handful of boating-related speeding infractions from the late 1990s and early 2000s.
In 2011, he was charged in Miami-Dade with disorderly conduct and obstruction, though the case was later dropped.
Today, Niv lives with Arison in New York where they split their time between a $13 million, 5,000-square-foot luxury SoHo apartment and a $5.4m, six-bedroom Georgian-style mansion in Bedford, just north of Manhattan.
In 2023, Niv and a group of neighbors sued the Bedford Planning Board and Verizon in an effort to block the installation of a 130-foot cell tower near his mansion.
In an affidavit, he described the home as a 50-acre haven for wildlife, including eagles and blue herons, and a place of ‘peace and solitude’ after years in the ‘fast-paced’ environment of New York City.
‘When we purchased our home, we never anticipated the Town of Bedford would attempt to place a 130-foot cell tower directly across the street from our property,’ he wrote, adding that the structure would resemble ‘a surveillance tower hovering over our property.’

The couple’s SoHo residence was featured in Architectural Digest in March 2022, which described the Mediterranean-inspired space as a ‘tour de force’ of design, complete with a custom-built, glass-enclosed solarium.
The apartment has also doubled as a salon of sorts for the philanthropic and art-world set, hosting star-studded gatherings and private events.
Martha Stewart was among the high-profile guests at one such function last year.

Arison, a publisher, philanthropist and art collector, founded the Tel Aviv-based magazine As Promised and serves on several prominent boards, including The Jewish Museum in New York and the Smithsonian American Women’s History Museum, where she is listed as a Founding Donor after contributing $1 million.
Her sister, Sarah Arison, is a major figure in the New York and Miami art worlds and currently serves as President of the Board of Trustees at the Museum of Modern Art.
The Arison fortune traces back to her grandfather, Ted Arison, who co-founded Carnival Cruise Line in the 1970s and built it into a global cruise empire.
His daughter – and Cassie Arison’s mother – Shari Arison later inherited a significant stake and expanded the family’s holdings, becoming one of Israel’s most powerful business figures – though she was no stranger to controversy herself.
During Shari’s tenure as controlling shareholder of Bank Hapoalim, Israel’s largest bank, the institution faced major investigations and ultimately paid more than $800 million to resolve US probes tied to tax evasion by American clients.

Her personal life also played out in public.
In 2004, she was embroiled in a custody dispute after relocating to Miami with her youngest son, prompting the boy’s father to file kidnapping charges. The case was later dismissed by a US federal judge.
The following year, another of Shari Arison’s former husbands, Ofer Glazer, was convicted in Israel of sexually assaulting two women – a household employee and a prospective tenant – and sentenced to six months in prison, serving roughly half that term before being released on parole.
While Cassie Arison’s parents inherited an empire, Niv’s parents built theirs from scratch.
Shlomi and Orly Alexander emigrated to the United States from Rishon LeZion, Israel, after the Yom Kippur War, arriving in Miami with little money and few connections.
Shlomi washed corpses in a morgue. Orly taught Hebrew at a Jewish day school.
In 1982, the couple founded Kent Security Services around their kitchen table. The company grew rapidly, becoming one of the largest security contractors in South Florida, providing guards for gated communities, Miami City Hall and high-profile private events, including parties at the Versace mansion.

As Kent expanded, Shlomi turned to luxury development. After a brief and unsuccessful nightclub venture in South Beach, he began building and renovating high-end homes across South Florida – a move that proved lucrative.
That shift would eventually intersect with his sons’ rise in brokerage. In 2012, Shlomi sold a waterfront estate on Indian Creek for $47 million – then one of the most expensive residential sales in Miami history – in a deal that involved Oren serving as the buyer’s agent.
The transaction became part of the brothers’ real estate origin story.
Before long, Oren and Tal were among the top producers at Douglas Elliman, closing record-setting deals and cultivating a clientele that included celebrities, athletes and billionaires — among them Ivanka Trump and Jared Kushner.
The trio were invited twice to the White House during President Donald Trump’s first term.
Their success unfolded alongside a conspicuous social life in New York and Miami, where they frequented elite parties and cultivated relationships with influential figures.
The rise was dramatic. The fall was swift.
In 2024, civil lawsuits alleging sexual assault began to surface. Months later, federal authorities arrested the three brothers on sex trafficking charges, accusing them of masterminding a decade-long scheme to lure, drug and assault dozens of women.
All three deny wrongdoing and insist any sexual encounters were consensual.
Their trial began in late January and is expected to run through early March.
Shlomi and Orly have been fixtures in the courtroom, alongside Alon’s wife, model Shani Zigron. Oren’s wife, Brazilian model Kamila Hansen, has appeared sparingly, while Tal’s wife, venture capitalist Arielle Kogut, filed for divorce within weeks of his arrest.
Niv Alexander attended court alone on February 11.
He kept a low profile, arriving late and occupying a bench behind his parents. He was later seen walking out of court by himself.
Testimony in the case continues Tuesday.
