Bernard Madoff's decades-long Ponzi scheme may have defrauded thousands of investors billions of dollars, but Kenneth Langone said "worst part" is the loss of life.
Mark Madoff, Bernie's oldest son, was found hanged in his New York City apartment in an apparent suicide on the second anniversary of his father's arrest.
Langone, a venture capitalist and investment banker of more than 30 years, said he was deeply saddened to see "the tragedy of a family disintegrated."
The Madoff sons and other family members had worked for Bernard L. Madoff Investment Securities, which crumbled when the Ponzi scheme was revealed.
Bernard Madoff, 72, was arrested on December 11, 2008, after his sons turned him in to authorities. Since then, Mark Madoff had not spoken with either of his parents, a source close to him said.
