Oren and Alon Alexander, both 39, and their older brother, Tal Alexander, 40, received their sentences Tuesday after federal prosecutors accused them of operating a decade-long scheme involving sexual exploitation, drugging and abuse.

The sentencing marks a major development in a case involving allegations from dozens of women who came forward with accounts of sexual assault and exploitation.

In addition to their 30-year prison sentences, the three brothers were each ordered to serve 10 years of supervised release after completing their prison terms.

The judge also directed all three men to participate in sex offender treatment programs while incarcerated.

Oren and Alon Alexander were each fined $300,000, while Tal Alexander was ordered to pay $350,000.

The court also ordered restitution, with the amount to be determined through further proceedings involving attorneys for both sides.

Oren Alexander received an additional financial penalty connected to his conviction for sexually exploiting a minor by distributing child sexual abuse material involving a 17-year-old girl in 2009.

The judge ordered him to pay an additional $50,000 immediately.

Federal prosecutors had urged the court to impose the maximum penalty of life imprisonment on all three brothers, arguing that the scale and duration of their crimes warranted the harshest available punishment.

Assistant U.S. Attorney Elizabeth Espinosa told the court that the government did not consider any one brother less responsible than the others.

Prosecutors described the operation as an extensive sex trafficking scheme that relied on the brothers’ wealth, social connections and access to luxury experiences to attract victims.

In a sentencing memorandum submitted before Tuesday’s hearing, prosecutors accused the brothers of repeatedly using the same methods to exploit women.

“They spent years designing, executing, and perfecting their playbook of luring victims with promises of luxury, drugging victims so they could not resist, and then forcibly raping them,” prosecutors wrote.

The government said the brothers continued these activities over several years, targeting numerous women.

“Over 70 women came forward with harrowing accounts of assault that stripped them of their dignity and autonomy,” prosecutors stated.

The allegations formed part of the government’s argument that the brothers had engaged in a prolonged pattern of predatory conduct rather than isolated criminal acts.

Defense lawyers for the Alexander brothers argued for substantially shorter prison terms.

They asked the court to impose 15-year sentences, the minimum penalty for the sex trafficking convictions, while continuing to maintain their clients’ innocence despite the jury’s guilty verdicts.

The defense position contrasted sharply with the prosecution’s request for life imprisonment.

Ultimately, the judge imposed 30-year sentences on each defendant, rejecting both the government’s request for the maximum punishment and the defense’s appeal for the minimum.

Before their arrests and prosecution, the Alexander brothers were known for their involvement in high-end real estate, particularly transactions involving wealthy clients and luxury properties.

Their criminal convictions represent a dramatic fall from their former positions in the industry.

The case has drawn attention to allegations that the brothers used their wealth and social status to gain access to women and facilitate abuse.

The sentencing also highlights the extensive number of women who reported alleged misconduct during the investigation.

With Tuesday’s ruling, each of the Alexander brothers now faces three decades in federal custody, followed by a lengthy period of court-supervised release.

The financial penalties and restitution requirements add further consequences to their convictions.

Although defense attorneys continued to assert the brothers’ innocence, the sentences follow a federal jury’s decision to find all three guilty on every count brought against them.

The court’s ruling concludes the sentencing phase of one of New York’s most closely watched federal sex trafficking prosecutions, while the final restitution amounts remain to be determined.
