The lawsuits were filed against an oil and gas company, a family fund and a trading company, alleging that they received funds from Bernie Madoff's investment firm. The suit against the family fund claims that Peter, Andrew, Mark and Shana acted "in complete dereliction of their management duties."
In a lawsuit filed against the Madoff family in 2000, Picard said the Ponzi scheme was "a family piggy bank" that funneled at least $198,743,299 of stolen customers' money to Peter, Andrew, Mark and Shana. The 2009 suit included an allegation that money was funneled to family members through fabricated purchases of stock, which they supposedly then sold for the cash proceeds.
Martin Flumenbaum, a lawyer for Mark and Andrew Madoff, told ABC News in July, "With respect to Mark and Andrew, the lawsuits are without merit both factually and legally."
Flumenbaum did not respond to a request for comment Thursday. Lawyers for Peter, Andrew, Mark and Ruth Madoff also did not immediately respond to requests for comment.
Through her lawyers, Ruth Madoff has denied any knowledge of her husband's fraud scheme. In a written statement on the day of her husband's sentencing, she said, "to say that I feel devastated for the many whom my husband has destroyed is truly inadequate."
This summer, when she was spotted on a Manhattan street by an ABC News producer, she didn't respond when asked if she had anything to say to her husband's victims.
"She was her husband's bookkeeper for all those years, and we wonder why she has not been prosecuted for all this," said Ronnie Sue Ambrosino, a Madoff victim who works as an advocate for other victims. Ambrosino said she hoped the arrests of Bongiorno and Crupi Thursday were "the beginning of justice being performed, albeit late, but better late than never."
Ambrosino said she felt it was a "travesty" that Madoff family members were not arrested as well. CLICK HERE to follow the ABC News Investigative Team's coverage on Twitter.
But victim DeWitt Baker, who said it was "outrageous" that no Madoff family members had yet been criminally charged, was philosophical about waiting. "They're certainly guilty. Everybody knows it. But you can't charge unless you have the kind of evidence that will stand up in court."
Said Irving Picard, "This is not an easy case to unravel."
