Wife who killed husband with rat poison in food to go free

A Pennsylvania woman who pleaded guilty to killing her husband by slipping rat poison into his food and drinks will be released from prison next week.

Fifty-three-year-old Joann Curley will be free on Monday after serving a 20-year sentence for the 1991 death of her husband, Robert Curley.

Prosecutors say Curley poisoned her husband with the chemical thallium for about a year so she could collect $300,000 in insurance policies and keep him from spending $1.7 million she won in a lawsuit.

The victim's sister, Susan Curley Grady, tells The Citizens Voice she feels Joann Curley should be serving a life sentence.

Joann Curley reached a plea deal in 1997 with prosecutors who intended to seek the death penalty.

Tests showed Robert Curley had 900 times the lethal dose of thallium in his system.
