Cleveland kidnapping survivor Michelle Knight detailed to Dr. Phil the torture she sustained at the hands of her captor, Ariel Castro. At one point, she remembered, he used an extension cord to hang her on the wall for days. "I was tied up like a fish, an ornament on the wall," Knight said. She was also chained to a pole in the basement and left with a motorcycle helmet over her head. Castro kept three women imprisoned in his house for a decade, and committed suicide in prison after being sentenced to life plus 1,000 years. The full interview airs Tuesday and Wednesday night.
