Margaret Rudin didn't look like a killer. With her gentle demeanour and a sweet smile, she seemed the most unlikely suspect in her husband's murder. However, it would be her actions after the murder, and a clue buried in her husband's Will, that would lead the police to believe that this Las Vegas grandmother was not as innocent as she appeared.

Ronald Rudin moved to Sin City in the 1960s and quickly amassed a small fortune in real estate development. He also dated and married a string of women. Margaret, his fifth wife, at first appeared to be a suitable match, but things would quickly turn sour. Their mutual distrust would cause Margaret to monitor Ron's business dealings, and Ron to suspect Margaret of only being interested in his money.

He made a change to his Will that showed how much he feared and distrusted his wife. It stated that if he died ‘by violent means’, and it was determined that one of his beneficiaries was responsible, that they should not receive anything.

After Ron's charred remains were found in the Nevada desert, the investigation to find his killer, and the trial to convict his wife would be something unlike Vegas had ever seen.
