Allison Mack Released from Prison After Serving Time for Role in Nxivm Sex Cult

Actress Allison Mack — who pleaded guilty to crimes stemming from her instrumental role in the Nxivm sex cult — has been released from prison early, according to federal records.

The Federal Bureau of Prisons website shows that Mack, 40, was released from prison on Monday. She had been serving time at the Federal Correctional Institution in Dublin, California, where other prominent actresses like Lori Loughlin and Felicity Huffman served their sentences for their role in the college admissions scandal.

The Federal Bureau of Prisons told PEOPLE in a statement Wednesday that Mack was released from custody via First Step Act (FSA) release — a Donald Trump-era law in which federal inmates can earn up to 54 days of "good conduct" credit for every year of their imposed sentence.

The agency also noted that inmates may release up to 12 months early if they complete the BOP's Residential Drug Abuse Program (RDAP), or via court order due to old age and medical conditions or clemency.

Mack was sentenced to three years in prison after she pleaded guilty to charges including racketeering and conspiracy for her role as a prominent leader within Nxivm, the dismantled, Keith Raniere-led self-help group some have characterized as a cult.

She faced a maximum of 40 years behind bars, though federal sentencing guidelines recommended a lower punishment of 14 to 17½ years.

However, prosecutors wrote to request Mack receive a lesser sentence than the guidelines called for, noting that she had "provided substantial assistance to the government" in its prosecution of her co-defendants.

Ahead of the sentencing, the actress — who is best known for her years-long role as Chloe Sullivan on The WB's early Superman-focused show — released a statement apologizing to everyone who was harmed by her involvement with Nxivm, calling it her "biggest mistake and regret" and committed to spend the rest of her life "working to make amends.”

Mack was first arrested on April 20, 2018, and was accused of recruiting sex slaves for Raniere, who co-founded the controversial self-help group Nxivm and its subgroup, DOS — described as an all-female secret society in which women allegedly were forced to be sexually subservient to Raniere.

Mack was among six people accused of sex trafficking, forced labor, racketeering, wire fraud and other charges for their roles in Nxivm, which operated out of Albany, New York, but suspended operations in 2018.

Federal investigators claimed Mack brought women into DOS, which was purported to be a female mentorship group to address members' weaknesses, but instead was used to take advantage of women sexually.

Raniere, 62, was also sentenced to 120 years in prison following his conviction on federal sex crimes and other charges in October 2020.

The Nxivm case first gained public attention in 2012 with a report in the Times Union. It went on to become the subject of scrutiny from law enforcement and journalists after it came under fire from Dynasty actress Catherine Oxenberg, whose estranged daughter, India, joined the group in 2011.
