Frank DiPascali—Bernie Madoff’s right-hand man, who federal investigators flipped as part of a plea bargain in 2009—died on Thursday of lung cancer, the New York Daily News reports. DiPascali was 58

“He was grateful to have been able to make some amends by helping the government these past few years,” his lawyer, Marc Mukasey, said. “Please respect the family’s privacy.”

DiPascali, once chief financial officer at Madoff Securities, was awaiting sentencing in Manhattan federal court on September 10th. Last year, U.S. District Judge Laura Taylor Swain described him as a “glib storyteller and an admitted and convicted perjurer.”

“Did you consider yourself to be pretty good at fooling people?” a defense lawyer asked DiPascali at one point, during trial. “Yes,” DiPascali said.
