Reports of a "black book" containing names of influential clients have also surfaced in the case, but its whereabouts have yet to be revealed.

Prosecutors say Gristina was overheard saying, during a five-year investigation, that she had made millions of dollars for arranging trysts for more than 15 years and that she had wealthy clients who "have an interest in not having this case go forward.”

Manhattan Assistant District Attorney Charles Linehan told the Judge Gristina "essentially assured anyone who asked that she has connections in law enforcement who will let her know if anything is going to come down, in terms of a criminal indictment."

When arrested in midtown Manhattan, investigators say she was with a friend and Morgan Stanley banker, and had just been to his office for a meeting to try to raise money to finance what prosecutors believe may be an online prostitution business. Morgan Stanley legal officials have decided to put the broker, David Walker, on administrative leave until the Manhattan district attorney’s office concludes its investigation.

Private investigator Vincent Parco said Gristina hired him because she wanted to make sure potential members didn't have criminal backgrounds.

"She has some legitimate business interests, nothing to do with the sex trade," Parco said according to MSNBC, "I know this sets off a lot of bells and whistles but it's really irrelevant," and added, "If somebody wants to pay a fee per month to use this site and they're an upscale gentleman who wants to meet an upscale lady, that's really their prerogative."

Gristina was arrested on Feb. 22 and has pleaded not guilty,and has since been jailed on a seven-figure bail for promoting prostitution.

She is due back in court on May 3rd. If convicted, she could face up to seven years in prison.
