CAPITAL REGION, N.Y. (NEWS10) — In June, former “Smallville” actress Allison Mack was sentenced to three years in prison for her role in NXIVM. Despite her court-ordered surrender date of September 29, the Bureau of Prisons Inmate Locator says she’s already serving her time.

It’s unclear why, but it appears she’s turned herself into the Federal Correctional Institution Dublin at least two weeks early. Her lawyers did not return NEWS10’s request for comment.

FCI Dublin is a low-security prison for female inmates in California’s East Bay. At sentencing, Mack’s attorneys requested that she be allowed to serve her time on the West Coast to be close to her family.

Mack, 38, was once part of the inner circle of NXIVM leader Keith Raniere. Prosecutors said she became a “master” for “slaves” she ordered, “to perform labor, take nude photographs, and in some cases, to engage in sex acts with Raniere.”
