READ about Piers Morgan's long career in journalism here.
Stacey Lannert was just 18 when she shot and killed her father. She was sentenced to life in prison without the possibility of parole, but was given a commutation in 2009. Part of that reason was the long history of sexual abuse by her father. She now has written a book, "Redemption," telling her story of survival, and her interview with Piers Morgan airs tonight.
"He didn't actually rape me until I was nine. That's the first time it happened," she says. "My father was an alcoholic and he would try to quit drinking and during those attempts our life was more peaceful, less violent." Hear her describe the moment she shot her father and her time in jail as well, tonight 9pmET/PT. Also airing tonight – Piers' sit-down with Larry Flynt.
