Washington, Jan 12 : Bernard Madoff, the prime accused of a 50 billion dollar wall Street investment fraud, even duped his sister, who is currently on the verge of selling her Florida home.

According to the New York Post. Madoff's sister Sondra Wiener, 74, is left with "nothing", revealed a neighbor in the BallenIsles Country Club, a gated Palm Beach enclave where Wiener and her husband, Marvin, live alongside such celebrities as Serena and Venus Williams.

It is being said that Wiener lost a whopping three million dollars.

"She lost millions in this whole thing," Fox News quoted a source as saying.

Wiener's son Davids said: "Yes, my family's a victim. More so than anybody else. It's very painful."

Wiener was one of five family members who received packages filled with jewels, allegedly mailed by Madoff and his wife, Ruth, on Christmas Eve.

The riches were collected by lawyers in recent weeks.
