Bernard L. Madoff said he never thought the collapse of his Ponzi scheme would cause the sort of destruction that has befallen his family.
In his first interview for publication since his arrest in December 2008, Mr. Madoff — looking noticeably thinner and rumpled in khaki prison garb — maintained that family members knew nothing about his crimes.
But during a private two-hour interview in a visitor room here on Tuesday, and in earlier e-mail exchanges, he asserted that unidentified banks and hedge funds were somehow “complicit” in his elaborate fraud, an about-face from earlier claims that he was the only person involved.
Mr. Madoff, who is serving a 150-year sentence, seemed frail and a bit agitated compared with the stoic calm he maintained before his incarceration in 2009, perhaps burdened by sadness over the suicide of his son Mark in December.
Besides that loss, his family also has faced stacks of lawsuits, the potential forfeiture of most of their assets, and relentless public suspicion and enmity that cut Mr. Madoff and his wife Ruth off from their children.
In many ways, however, Mr. Madoff seemed unchanged. He spoke with great intensity and fluency about his dealings with various banks and hedge funds, pointing to their “willful blindness” and their failure to examine discrepancies between his regulatory filings and other information available to them.
“They had to know,” Mr. Madoff said. “But the attitude was sort of, ‘If you’re doing something wrong, we don’t want to know.’ ”
