The younger brother and business partner of disgraced financier Bernard Madoff pleaded guilty on June 29 to charges he doctored documents, but insisted he knew nothing about his brother’s historic Ponzi scheme and was “in total shock” when he found out about it.

An emotional Peter Madoff, 66, entered the plea in a deal that permits him to remain free on $5 million bail pending his Oct. 4 sentencing. He agreed not to contest a 10-year prison sentence.
