Todawe all stopped to watch an incredible human drama in a cleveland courtroom. A tiny woman, a survivor, summoning the powering strength to stair down the man who had abused her for 11 years. When she finished in the bizarre turn, the kidnapper blamed his victims and insisted he was not a monster. He was somehow misunderstood. Alex perez takes us through the stunning showdown. Reporter: She was his first victim, enduring 11 long years of abuse and torture. Today michelle knight stood tall and faced down the man who held her captive. Day turned into night, night turned into day. Years turned into eternity. I knew nobody cared about me. He told me is that my family didn't care. Reporter: Knight was 21 years old when castro lured her in with promising of a puppy. Amanda berry 16 when she was abducted. Today she's 27. gina DeJesus now 23. Gina was my mate. She never let me fall. Reporter: Michelle was the only victim who came to court. Today she was a tiny tower of strength. As she spoke, ariel astro's eyes never left her. This is the moment he registered emotion. I spent 11 years in hell. Your hell is just beginning. I will yefr come all this that happened but you will face hell for eternity. Reporter: Today a new glimpse into what those women endured. The rusty chains he used to restrain them. They all kept diaries, fearing they would never make it out ali alive. In a rambling statement castro implied he was the real victim insisting he never abused any of the women. I'm not a violent predator. I'm not a monster. I'm a normal person. I'm just sick. Reporter: Astro became emotional talking about his daughter with amanda berry but the judge was unmoved. Castro will never be allowed to see jocelyn again. He was sentenced to life in prison plus 1,000 years. Now his victims are moving forward. Gina's cousin telling the court of every day milestones. She laughs, she swims. She dances, and more importantly, she loves and she's loved. Reporter: For michelle knight, standing up there today, a giant step forward. After 11 years, I am finally being heard and it's liberating. Thank you all. I love you. God bless you. Reporter: And even though michelle did shed tears in that courtroom her strength never wavered. All of the strength she has gotten since she was freed has taught her there is still more good an evil. It was a stunning day. Thank you, alex.
