Cleveland (CNN) -- When her chance came, kidnapping victim Michelle Knight lit into Ariel Castro, the man who held her captive and raped her in his Cleveland home for a decade. In handing down a sentence of life without parole plus 1,000 years in prison, Judge Michael Russo told the kidnapper there was no place in the world for his brand of criminal. The charges stem from his kidnapping, rape and assault of three women: Knight, abducted in 2002; Georgina DeJesus, abducted in 2004; and Amanda Berry; abducted in 2003. Castro is the father of Berry's 6-year-old girl, DNA tests have confirmed. All three women kept diaries with Castro's permission, providing many of the details of their abuse. Ariel Castro's son: I won't visit dad in prison Berry and DeJesus, who did not attend the hearing, sent representatives to issue impact statements on their behalves, while Knight chose to address her abductor head-on. In a pre-sentencing evaluation, Dr. Frank Ochberg, a pioneer in trauma science, wrote that Knight suffered "the longest and most severely." "At other times, she interceded when Castro sought to abuse Gina, interposing herself and absorbing physical and sexual trauma. 'Happy household' Castro even claimed that no one cared enough about Knight to search for her after she disappeared. I never tortured them." When Castro finished, Russo dubbed him a "violent sexual predator" and thanked Knight for showing "remarkable restraint" during the hearing. Testimony from authorities and mental health experts didn't jibe with Castro's recollection, however. Police recalled how the women were forced to play Russian roulette and how Castro would throw money at them after raping them. Det. David Jacobs of the Cuyahoga County Sheriff's Office testified he'd also show a gun "to the girls as a form of control." The back door was outfitted with an alarm, bedspreads and curtains obscured parts of the home, a porch swing was placed in front of the stairs leading to the rooms where Castro held the women and girl hostage. Burke also described a handwritten letter in which Castro claimed he had been sexually abused as a child and wrote, "I am a sexual predator." You saved us!' When the captive women realized they were police, Knight "literally launched herself" onto an officer, "legs, arms, just choking him. She just kept repeating, 'You saved us! " Johnson said. The women were described as scared, pale, malnourished and dehydrated when they were rescued. Dr. Gerald Maloney, who was in the emergency room when the victims arrived, said Knight requested that no male physicians attend to her. Several witnesses said the women told them stories of being physically abused and deprived of food. Det. Andrew Harasimchuk told the judge the women were raped "vaginally, orally and anally" during their captivity. Multiple officers testified that Castro appeared to show no remorse for his crimes, and prosecutor Anna Faraglia said he "tormented" his victims by allowing them to watch vigils held in their honor and even attended some. Outlining the emotional toll their captivity took on them, Ochberg said the women will be subjected to life sentences of their own. Ochberg's evaluation -- using statements, medical records, videotaped interviews and transcripts -- painted a horrifying picture of physical and emotional abuse at the hands of Castro, including brutal beatings and repeated rapes that resulted in pregnancies that he would terminate by punching the women in the stomach. Child custody rights for rapists? Forensic psychiatrist Dr. Gregory Saathoff testified in court that the women's ordeal was a "complete and comprehensive captivity" and said when he first learned of Castro's crimes, he was compelled to write, "The scope and magnitude of Ariel Castro's crimes is unprecedented." Asked if he felt Castro suffered from mental illness -- something the defendant repeatedly asserted during his statement -- Saathoff was firm in saying that an examination showed Castro suffered from "no psychiatric illness whatsoever." 'Thank you, victims' In addition to Judge Russo's guarantee that he "will never be released from incarceration during the period of his remaining natural life for any reason," Castro was also hit with a forfeiture of property and fined $100,000. As the judge sentenced him, Castro took issue with the aggravated murder charge related to the termination of his victims' pregnancies, saying there was no evidence those incidents occurred. Russo reminded him that he had already pleaded guilty, and Castro said he did so only to save his victims further trauma. "In your mind, there was harmony and a happy household," Russo said. As the hearing came to a close, Castro turned around in the court and glanced at family members of the victims. "Thank you victims. In each case, according to court documents, Castro lured the women into his car with the promise of a ride. The women and girl were freed in May after Berry shouted for help while Castro was away. A neighbor heard her cries and let Berry use his phone to call police. "Help me, I am Amanda Berry," she frantically told a 911 operator. In early July, Berry, DeJesus and Knight released a YouTube video offering their thanks to all those who have helped them since they were freed.
