Lawyers for the state of New Mexico say that Marc Correra received $14 million in placement agreements from the companies.
The Correras have denied any wrongdoing. While a federal grand jury has investigated the allegations, no criminal charges have been filed.
Marc Correra, who reportedly left New Mexico for France in 2009, could not be located for comment for this article. Ralph Siciliano, an attorney for Correra, declined to comment.
The investigation ended Richardson's aspirations to return to the Cabinet.
Richardson had been energy secretary and ambassador to the United Nations under President Bill Clinton. Obama nominated him at the end of 2008 to head the Department of Commerce.
Richardson withdrew after it was reported that Republicans planned to raise questions about the New Mexico probe during his confirmation hearings.
As authorities were looking at the Correras, Maryland officials took notice.
"The background investigation began to indicate that there were potential allegations about irregular activities involving Correra in New Mexico," said Holly Knepper, deputy counsel at the Maryland State Lottery Agency.
The agency asked Moldenhauer "on numerous occasions" to swap out Marc Correra's $3 million and replace it with his own money, Knepper said. He never did.
"It became of concern that with Correra on [the Baltimore City Entertainment Group's] proposal as a principal that BCEG would not be able to qualify," Knepper said.
Asked by The Baltimore Sun in August 2009 about his relationship with Marc Correra, Moldenhauer said Correra had "expressed an interest" in the Baltimore casino but "we never really got to the stage where it reached a formality of him becoming a partner."
In fact, Moldenhauer had submitted paperwork to the Lottery Agency showing that Marc Correra had a 46.25 percent stake in the group, according to court documents filed in Baltimore. Moldenhauer never amended the filing.
Moore says she has an affidavit from Correra indicating that he has no claim on the $3 million fee.
But in papers filed in the Baltimore court, the lawyers for New Mexico say the New Mexico State Investment Council "believes it will be able to show that this $3 million payment was funded by the bogus placement agent fees paid to Marc Correra with NMSIC funds."
It was Maryland lottery officials who had tipped off the New Mexico attorney general's office to Correra's involvement in the Moldenhauer group. The Maryland officials had contacted New Mexico in the search for potential claimants to the fee.
Michael Cryor, a former partner in Moldenhauer's group, said he understood that the $3 million was money that Correra owed Moldenhauer from an unrelated deal.
"That story got harder and harder to track," said Cryor, who is also claiming a portion of the money.
He said Moldenhauer told him consistently that Correra was not a part of the Baltimore casino deal. He said he was surprised to learn that court papers indicated otherwise.
"I can't begin to tell you how crazy this is," Cryor said.
