Federal prosecutors are scrutinizing a growing array of people tied to Sam Bankman-Fried’s collapsed cryptocurrency empire, including his father, his brother and former colleagues, as part of a rapidly expanding investigation into one of the biggest American financial crime cases in more than a decade, the New York Times reported. The U.S. attorney’s office in Manhattan has created a special task force to pursue its investigation into the collapse of FTX, the crypto exchange founded by Mr. Bankman-Fried. More than half a dozen prosecutors, led by Damian Williams, the U.S. attorney for the Southern District of New York, are building the criminal case and tracking down the billions of dollars in customer money that Mr. Bankman-Fried has been charged with misappropriating. In recent weeks, prosecutors have had talks with lawyers representing a dozen former executives and employees at FTX and Alameda Research, the hedge fund Mr. Bankman-Fried also founded. Prosecutors have also examined the role of Mr. Bankman-Fried’s family members in his business empire. The collapse of FTX has forced virtually everyone in Mr. Bankman-Fried’s immediate orbit to seek legal counsel as the investigation intensifies and prosecutors weigh bringing more charges. Defense lawyers at the law firms Mayer Brown, Steptoe & Johnson, and Covington & Burling each represent multiple former FTX executives who may have information to contribute. The FTX investigation could also ensnare companies that either received money from the exchange or lent it funds. The collapse of FTX last year set off a crisis at the crypto lending firm Genesis, which was recently charged with securities law violations by the S.E.C. And in late January, a bipartisan group of senators sent a letter to Silvergate, a bank that did business with FTX, asking company officials whether they were aware of the exchange’s misuse of customer money.
