NEW YORK - Imprisoned financier Bernard Madoff won't seek to attend his son's funeral out of consideration for the privacy of his son's wife and four children, his lawyer said yesterday.

Attorney Ira Sorkin said Madoff instead will mourn privately at the North Carolina prison where he's serving a 150-year sentence for his fraud conviction in what authorities have called history's largest Ponzi scheme.

Madoff's older son, Mark Madoff, 46, hanged himself early Saturday in his Manhattan apartment.

Sorkin wouldn't say whether Madoff considered asking to attend his son's funeral. The lawyer would say only: "Mr. Madoff will not be attending the funeral out of consideration for his daughter-in-law's and grandchildren's privacy. He will be conducting a private service on his own where he is presently incarcerated."

Mark Madoff was found hanging from a dog leash in his apartment. His 2-year-old son was found asleep in an adjacent room.

The actions of Mark Madoff, along with those of his brother, Andrew Madoff, and his uncle Peter Madoff, have been studied by investigators trying to learn how Bernard Madoff was able to carry out such a large fraud without them knowing about it. Madoff's brother and sons all held management positions at the family investment business.

In November 2008, Madoff confessed to his sons that his purported $60 billion investment business was a sham and that he had only several hundred million dollars of investors' money left.

In court papers, a lawyer for the sons has portrayed his clients as whistleblowers who alerted authorities as soon as their father revealed the fraud to them. Neither son, nor Madoff's brother, has been charged criminally, and authorities have said no charges are imminent.
