TV Polygraph Operator Dan Ribacoff’s International Investigative Group Allegedly Bilked Client

All in the family: International Investigative Group proprietors Daniel D. Ribacoff, daughter Lisa J. Ribacoff, and son Lance Ribacoff

Lawsuits filed in Nassau County, New York allege that TV polygraph operator Daniel D. “Dan” Ribacoff and his “family owned & operated” private investigation company, International Investigative Group, behaved negligently and bilked the plaintiffs out of millions of dollars. Kathianne Boniello reports for the New York Post:

A prominent PI firm was so eager to keep the cash coming in from rich clients, it turned a blind eye to its private eyes acting “like drunken fraternity brothers,” a new lawsuit charges.

Dan Ribacoff, a polygraph expert who bills himself as one of the top private investigators in the country and has appeared on TV shows like “Impractical Jokers” and “The Steve Wilkos Show,” displayed “willful ignorance” and took no action as the gumshoes who worked for him went rogue, according to the $10 million claim.

Ribacoff’s Long Island-based International Investigative Group exchanged thousands of text messages with underlings, encouraging them to double bill and pad hours to run up the tab for wealthy clients like Patty Hearst’s granddaughter Gillian Hearst and ice cream company heir David Smith, according to court papers.

A prior lawsuit, David M. Smith vs. International Investigative Group et al., was filed in the Nassau Supreme Court on 31 May 2019 under index number 0607393/2019 and seeks damages of more than $18 million. The 48-page statement of complaint (2 MB PDF) in that litigation cites causes of action including breach of contract, fraud, gross negligence, and “breach of the covenant of good faith and fair dealing.”

In December 2019, a guest on the Steve Wilkos Show, for which Dan Ribacoff provides polygraph services, attempted suicide after Ribacoff falsely accused her of lying when she denied having burned her infant daughter. In fact, no one had burned the daughter, and lesions that appeared on her leg were the result of a ringworm infection.
