Speaking in an anti-porn campaign video Elizabeth Smart, 28, said Brian Mitchell’s passion for porn led him to snatch her.
She added that when he watched the videos it “just led to him raping me more”.
Ms Smart was kidnapped by twisted Mitchell at the age of 14 when he and his wife Wanda Barzee broke into her home in Utah, USA, and snatched her from her room.
She was then repeatedly raped over a nine month period and was forced to watch sexually explicit films.
Smart has now argued that Mitchell, who was 57, was fuelled by his passion for porn when meted out the horrific abuse.
She said: “All I know is that pornography made my living hell worse.”
