LAS VEGAS -- A former socialite known as Las

Vegas' Black Widow was sentenced to life in prison Friday for the murder of her millionaire husband.

"You're going to be locked away in the cold confines of your prison cell, never to be heard from again," District

Judge Joseph Bonaventure told 58-year-old Margaret

Rudin.

Rudin showed no emotion and offered no remorse

She was convicted in May of murdering her husband, Las

Vegas real estate developer Ron Rudin, in 1994. His skull

and some charred bones were found in 1995 in the desert

about 45 miles from Las Vegas.

Prosecutors said she killed him to get her 60 percent

share of his $11 million fortune.

She did not know that he had signed a secret directive in

1991 saying that if he died violently, anyone found

responsible would be cut out of his estate, prosecutors

said.

The Rudins married in 1987; it was the fifth marriage foreach.

Margaret Rudin's attorneys had asked for a new trial,

arguing that her former lawyer mishandled the case and

accusing the jury of misconduct.

But the judge rejected those arguments Friday as Rudin's

"constant legal gyrations," and noted she was represented

at her trial by two of the top defense attorneys in Las

Vegas.
