In a striking development just weeks before a federal trial, prosecutors have broadened their case against the Alexander brothers, introducing new charges against two of them. The allegations claim that the brothers sexually assaulted a woman who was unable to consent, adding a dramatic twist to the unfolding legal saga.

The latest superseding indictment accuses twin brothers Oren and Alon Alexander of committing this heinous act in January 2012 on a cruise ship registered in the Bahamas, which had set sail from and returned to the United States. This charge is the newest addition to a series of accusations as the brothers remain detained, awaiting their day in court in New York.

This new charge represents a major intensification of a case that has been gaining momentum since the brothers’ initial arrest in December 2024. Federal prosecutors have been steadily building their case, filing multiple indictments to strengthen their position as the trial approaches.

The Alexander brothers—Oren, Alon, and their elder sibling Tal—are accused of orchestrating a sprawling, decades-long scheme involving drugging and sexually assaulting women in various upscale locales, including Miami, New York, and the Hamptons. Despite these serious allegations, the brothers have consistently maintained their innocence.

According to previous court filings, the brothers and their alleged co-conspirators are accused of luring women with promises of luxury travel, accommodations and access to high-end social events before allegedly incapacitating and sexually assaulting them, sometimes involving multiple men. Earlier filings also included allegations involving additional victims, including at least one minor.

Tal and Oren Alexander are prominent luxury real estate brokers who co-founded the firm “Official” after rising through the ranks at Douglas Elliman, while their brother Alon Alexander worked in the family’s private security business. Prosecutors have alleged the brothers used their wealth, industry status and access to exclusive events to attract women to trips, parties and dates before the alleged assaults occurred.

Defense attorneys for Oren and Alon Alexander have moved to dismiss the new charge, arguing the indictment is legally flawed because it does not allege the brothers knowingly engaged in sex with a woman they knew was physically incapacitated, according to amNY.

“This is a fatal flaw requiring dismissal of the indictment,” the attorneys wrote in a joint court filing cited by amNY, arguing prosecutors are improperly charging the same alleged January 2012 incident under different statutes.

During a court appearance, Zach Intrater, an attorney for Oren Alexander, criticized the timing of the new charge, telling the judge, “These men’s lives depend on this,” according to amNY. Judge Valerie Caproni rejected that argument, responding, “These are all serious charges,” the outlet reported.

Prosecutors acknowledged in court filings that the word “knowingly” was omitted from the indictment and said they intend to seek another superseding indictment to correct the issue, amNY reported.

Caproni has also ruled on several other pretrial disputes, including a dispute over whether some alleged victims can testify anonymously — a request she granted over defense objections, according to amNY. Prosecutors have said the trial could stretch into late February or early March.

Court records show the brothers are being held at the Metropolitan Detention Center in New York City, with jury selection set to begin Jan. 20 and the trial scheduled to start Jan. 26.
