Prosecutors probing Bernard Madoff's massive fraud are determined to leave his wife with almost nothing after telling a Manhattan court that they consider more than $100 million in assets, most of it listed in her name, the fruits of her husband's crimes.

The government even included a $39,000 Steinway piano and $65,000 in silverware, both owned by Ruth Madoff, in items it said it will try to force the Madoffs to forfeit. The list was in a three-page document filed in US District Court.

Bernard Madoff, 70, has been living in a small cell at the Metropolitan Correctional Center in lower Manhattan since he pleaded guilty on Thursday to securities fraud, perjury and nine other charges. He could be sent to prison for up to 150 years at a June sentencing.
