Smallville actress Allison Mack helped convict NXIVM sex cult leader Keith Raniere by giving prosecutors an audio tape of him talking about branding his recruits, court documents reveal.
The 38-year-old actress, who pleaded guilty in 2019, will be sentenced on June 30 for her role as a 'slave master' in the upstate New York cult that saw women recruited to be Raniere's sex slaves and then branded with his initials.
Mack, who has been on house arrest in California since her guilty plea, is facing up to 17 years in prison.
In a pre-sentencing memo on Monday, federal prosecutors asked the judge to hand down a reduced sentence given Mack provided the tape that helped bolster their case against Raniere.
A transcript of the tape, which was included in the court filing, showed Raniere and Mack discussing the branding ceremony.

'Do you think the person who's being branded should be completely nude and sort of held to the table like a, sort of almost like a sacrifice? I don't know if that, that's a feeling of submission, you know,' Raniere asked.
He also suggested filming the branding to be used as 'collateral' in a bid to stop women leaving the cult.
Raniere went on to describe how the woman should be in a 'vulnerable position' for the branding.
'Laying on the back, legs slightly, or legs spread straight like, like feet, feet being held to the side of the table, hands probably above the head being held, almost like being tied down, like sacrificial, whatever,' he said.
'The person should ask to be branded. Should say, please brand me it would be an honor, or something like that. An honor I want to wear for the rest of my life, I don't know.
'And they should probably say that before they're held down, so it doesn't seem like they are being coerced.'
Raniere, who was sentenced last October to 120 years in prison, had long maintained he did not have any involvement in the branding ritual.
Prosecutors repeatedly referenced the tape during his trial.
