Addressing the court before his sentencing Ariel Castro said: "I know it's wrong and I'm not trying to make excuses I know I'm 100% wrong for doing that. But I'm trying to say I'm not a violent person.
He continued: "I was driven by sex.
"Amanda [Berry], she got in my car without knowing who it was, I'm not trying to put in her, but I'm just saying I'm not a violent predator, I'm not a monster. I'm just sick, I have an addiction, just like an alcoholic has an addiction."
In an emotional victim's statement Michelle Knight has told her captor of 11 years Ariel Castro that she, "will overcome all this that happened."

Ariel Castro has spoken to the court ahead of his sentencing for 937 charges related to the kidnap of three women for over a decade in his home.
Castro told the court:
"I stated before that I was a victim of sex when I was a child. This led me into viewing pornography for my whole life...These people are trying to paint me as a monster and I'm not a monster, I'm sick. My sexual problems have been so bad on my mind, I'm impulsive."
"I believe I am a victim to porn."
Michelle Knight was the only one of Ariel Castro's victims to speak herself in court, she said: "Days never got shorter, days turned in to nights, nights turned in to days. The years turned in to eternity.
"Nobody should ever have to go through what I went through.
Through tears she told Castro: "I spent 11 years in hell, now your hell is just beginning. I will overcome all this that happened, but you will face hell for eternity."
