Former partner Stuart Rosenfeldt has filed a civil suit alleging that Rothstein ran a covert investment scheme on the side and may have walked away with "substantial sums'' put up by investors. Rothstein attracted investors by promising huge returns and selling legal settlements he said he had reached, but at least some of those settlements did not exist, according to Rosenfeldt's suit.
Before his trip to Morocco, Rothstein was an important figure on the South Florida social and political scene. Rothstein was a major contributor to the Republican Party, as reported by ABC News earlier this month. The political contributions, which went to both state Democratic and Republican parties and individual politicians, have been returned. Rothstein gave $9,600 to Republican Gov. Charlie Crist's campaign for the U.S. Senate and $6,000 to Democrat Alex Sink's gubernatorial campaign.
Rothstein gave big to charitable organizations and hospitals as well. All together, he donated $1.8 million to two Ft. Lauderdale hospitals -- $800,000 to Joe DiMaggio Children's and $1 million to Holy Cross.
Alison W. Lehr, assistant U.S. Attorney in Florida's Southern District, filed the amended complaint for forfeiture on Monday. A spokesperson for the office, Alicia Valle, declined comment.
Those who say they were victimized by Rothstein's alleged fraud will benefit from the seizures. Scherer said, "It will greatly help my clients start to get some of their money back."
Scherer said his clients have suffered $100 million in losses. He said that other alleged victims he is not representing have lost another $400 million and expects the total dollar amount to grow. The Florida-based attorney also says that Rothstein and TD Bank associates weren't the only ones involved. He said, "I think that others will be included [in the suit] as we learn more."
FBI and IRS investigators continue to collect information on the case, sources close to the investigation told ABC News.
