Now, some of those winnings - as well as ownership of Curlin - are potential assets that could be grabbed by federal prosecutors and angry plaintiffs.
A federal grand jury this week indicted two attorneys who own 20 percent of Curlin, charging them with conspiring to commit wire fraud in representing more than 400 people in the suit over the diet drug fen-phen.
Federal prosecutors want the men to forfeit any assets they have to pay restitution to their former clients. And, a lawyer for the former clients claims Curlin was bought with money that belonged to the fen-phen clients.
Shirley Cunningham Jr., 52, and William Gallion, 56, bought Curlin for $57,000 as a yearling through their Midnight Cry Stable.
They sold controlling interest in the horse in February for a reported $3.5 million to a group comprising Jess Jackson, founder of Kendall-Jackson wines; Satish Sanan's Padua Stables; and George Bolton, an investment banker. Gallion and Cunningham retained a minority interest and were in the winner's circle after the 3-year-old won the Preakness on May 19.
Angela Ford, a Lexington, Ky.-based attorney representing many of the people in a civil case against the two lawyers, said if the attorneys bought the racehorse with money taken from their former clients, it could lead to all or part of the horse being sold, with the money being used to repay the former clients.
To lay claim to Curlin, both the former clients and prosecutors would have to show Gallion and Cunningham used money that rightfully belonged to the fen-phen clients to purchase the horse.
The grand jury, after an investigation by the FBI, also demanded that Cunningham and Gallion give up $46 million in misappropriated funds and more than $21 million in fees put in a charitable fund. They were charged Thursday, along with Lexington lawyer, Melbourne Mills Jr., who does not own an interest in Curlin.
Any collected funds would go to the federal government, which would use some of it for restitution to any victims.
Gallion, Cunningham and Mills were already found to have defrauded clients in the $200 million fen-phen settlement and were temporarily suspended from practice.
