Bernie Madoff's Daughter-in-Law Speaks Out (Video)
Bernie Madoff was convicted in June 2009 for running the largest Ponzi scheme in American history.
Now, over two years later, the widow of Madoff's son, Mark, who committed suicide on Dec. 11, 2010, Stephanie Madoff Mack sat down for an exclusive interview to discuss her father-in-law.
In a promo for the interview, Mack tells ABC News' Chris Cuomo that if she saw him today, she'd "spit in his face" and tell him that she hold him responsible for Mark's death.
In another video of the interview, which airs on 20/20 Friday at 10 P.M. ET, the widow says she wrote a letter to Madoff, who is currently serving his 150-year sentence in a North Carolina prison, hoping to make him feel guilty about the life he was missing.
"He wrote, "As you can imagine, I am quite the celebrity, and am treated like a Mafia don. They call me either Uncle Bernie or Mr. Madoff. I can't walk anywhere without someone shouting their greetings and encouragement, to keep my spirit up. It's really quite sweet, how concerned everyone is about my well being, including the staff...It's much safer here than walking the streets of New York," says Mack.
