'It Wasn't Enough For Him!' Elizabeth Smart Exposes Horrific Sex-Fueled Kidnapping

Elizabeth Smart is reliving her cruel and painful captivity for a new anti-pornography campaign, RadarOnline.com has learned.

Smart, 28, detailed the night she was taken from her Salt Lake City, Utah home in 2002 in a video for Fight the New Drug, and revealed that her captor Brian David Mitchell was fueled by pornographic magazines.

The new mom explained that Mitchell began raping her immediately after she was kidnapped, and when he discovered pornography, her sexual assault became worse.

"It just led to him raping me more, more than he already did, which was a lot," she said.

"Looking at pornography wasn't enough for him," she continued. "Having sex with his wife after looking at pornography, it wasn't enough for him."

"And then it led him to finally going out and kidnapping me," she speculated. "He just always wanted more. I can't say that he would not have gone out and kidnapped me had he not looked at pornography."

"All I know is that pornography made my living hell worse," she affirmed.

Smart was rescued from her nine-month captivity in March 2003. She testified in October 2009 that she was raped three to four times daily, and in May 2011, Mitchell was sentenced to two life terms for his crimes against her.

"I have gone on to become an advocate for abuse prevention, an advocate against pornography," Smart now said in the video. "I witnessed firsthand just how damaging it is."

"When I take a step back and I look at my life as a whole, I have had a pretty incredible, wonderful life and I wouldn't trade it for anything," she concluded. "I'm happy now and I couldn't imagine my life any different from how it is now."
