U.S. Attorney Preet Bharara called "the plot that led to the brutal death of Ben Novack ... a family affair." While Janet Difiore, district attorney of Westchester County in New York said it was "short of a calculated plot."
"The killing of Ben Novack was not a spur-of-the-moment crime of passion. It was the end game of considerable planning," said George Venizelos of the FBI's New York field office.
According to The Associated Press, the Novack's had an "eventful marriage" that included bondage, sex games and bouts of violence.
In 2002, Novack claimed his wife orchestrated a home invasion robbery that left him tied to a chair for 24 hours. He decided not to prosecute when she told police it was an episode in their unusual sex life, the AP reported.
Narcy Novack also claimed her husband once broke her nose, then took her to a plastic surgeon to repair it. When she woke, she said, she had breast implants she hadn't asked for, the police report said. No charges were filed.
Under her husband's will, Narcy Novack stands to inherit his entire fortune, which is at least $6 million. If she were to lose the estate, most of it would go instead to daughter May Abad and into trusts for her two teenage sons.
