The National Futures Association on Monday froze the funds of the Iowa-based brokerage Peregrine Financial Group, Inc, which does business as PFGBest, after discovering an estimated $220 million shortfall in PFGBest's customer accounts. The NFA had said in an affidavit that Wasendorf "may have falsified bank records."

Wasendorf, 64, is reported to be in a coma after a suicide attempt Monday morning, according to a complaint filed by the Commodity Futures Trading Commission on Tuesday that accuses Wasendorf and Peregrine of fraud.
