(Bloomberg) -- Ghislaine Maxwell, the British socialite convicted of engaging in a 10-year sex-trafficking scheme with former boyfriend Jeffrey Epstein, deserves to spend 30-55 years in prison, federal prosecutors said.

The government submitted its sentencing recommendation on Wednesday in federal court in Manhattan, a week after Maxwell filed her own memo asking that she be given less than six years in prison. US District Judge Alison Nathan, the federal judge who presided over the case and is now on the 2nd US Circuit Court of Appeals, will sentence Maxwell on June 28.

Maxwell, 60, was found guilty in December on five counts, including sex-trafficking of a minor, a verdict that was hailed as long-delayed justice for Epstein’s victims. Four women took the stand during their trial and described their abuse by the couple.

Prosecutors called the Oxford-educated Maxwell a “sophisticated predator” who befriended the girls and often acted like a big sister, taking them shopping or to the movies, before forcing them into sexual encounters with Epstein. At least two victims testified Maxwell participated in some of the abuse.

According to federal sentencing guidelines calculations, Maxwell’s crime warrants a sentence of 24 years to 30 years.

In her own submission, Maxwell argued for leniency, saying she and her siblings had been mentally and physically abused as a children by their father, British publishing tycoon Robert Maxwell. She also repeated her argument at trial that prosecutors scapegoated her for the crimes of Epstein, with whom she said she had not had any involvement for nearly two decades. 

Epstein was found dead in his Manhattan jail cell in 2019 while awaiting trial on his own sex-trafficking case.

The case is US v. Maxwell, 20-cr-330, US District Court for the Southern District of New York (Manhattan).
