Former NXIVM president Nancy Salzman has begun her three-and-a-half year prison sentence. Salzman is expected to serve her time at Alderson, a West Virginia federal facility that once housed Martha Stewart and is nicknamed “Camp Cupcake.”

Salzman was expected to report to prison on Monday, a national holiday. On Tuesday, the U.S. Bureau of Prisons listed Salzman as a prisoner at another federal correctional facility in Hazelton, W.Va.

Salzman, 67, of Halfmoon, who spent two decades as NXIVM leader Keith Raniere’s second-in-command in the cult-like personal growth organization based in Colonie, is expected serve her sentence at Alderson federal prison camp, which holds 645 inmates and has been described as a more cushy environment than other federal lock-ups that hold more violent inmates.

Alderson, located in Greenbrier County in southern West Virginia, is a more than 10-hour drive from Salzman’s home in southern Saratoga County. Alderson, the oldest federal prison facility for women in America dating to 1928, is where Martha Stewart served her five-month prison stint in connection with a well-timed stock sale scandal.

Other high-profile inmates over the years have included legendary jazz singer Billie Holiday, who served time at Alderson between 1947 and 1948 for narcotics possession; Iva Toguri D’Aquino, the World War II broadcaster dubbed “Tokyo Rose” who served time there for treason (she was later pardoned), and Lynette “Squeaky” Fromme, a member of the notorious Manson family cult led by mass murderer Charles Manson. Fromme was convicted of trying to assassinate President Gerald Ford in 1975.

A former inmate at Alderson, reached by the Times Union through Wall Street Prison Consultants, a group that helps defendants transition into incarceration and take advantage of programs to get out early, said while the camp is “easy time” compared to higher security facilities, there are no pools or tennis courts or horseback riding in federal prison camps as there once may have been decades ago.
