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."
One of Ariel Castro victim's was seen in court seen embracing a member of the prosecution team ahead of his sentencing.
Michelle Knight was held captive for 11 years by the former school bus driver, who abducted and sexually abused her.
Castro was sitting at the front of the courtroom when Knight arrived. Ms Knight is expected to give a victim statement in court shortly. Castro is expected to be sentenced to life in prison.
The court will be shown a 3D model of Ariel Castro's home in Cleveland, Ohio where he imprisoned and abused three women for a decade as part of today's hearing.
Ariel Castro has entered the courtroom in the US state of Ohio where he is due to be sentenced for 937 charges including rape and aggravated murder.
Dressed in orange prison garb and ankle chains, Catro has mainly been giving one-word answers to the judge's questions.
Ariel Castro will speak during today's sentencing, according to local TV station WKYC.
At least one of his captives - most likely Michelle Knight - will also speak during the hearing.
One of the women who was imprisoned for years in the Cleveland home of Ariel Castro has written to local police officers thanking them for their work.
NBC News displayed a copy of the letter from Michelle Knight in which she writes that "life is tough, but I'm tougher".
Cleveland police posted the handwritten note on their Facebook page, but it has since been removed.
Two of the Cleveland kidnap victims detailed years of incarceration and abuse in personal diaries, a prosecutor has revealed.
In a sentencing memo file submitted last night, prosecutor Timothy McGinty said the diaries speak of "forced sexual conduct, of being locked in a dark room ... [and] of the dreams of someday escaping and being reunited with family".
Ariel Castro, who has pleaded guilty to 937 charges including rape and aggravated murder, is due to be sentence later today.
The Ohio prosecutor has announced a 977-count indictment against a man charged with holding three women captive and abusing them in his home in Cleveland, Ohio, for around a decade, according to the Reuters news agency.
Ariel Castro had already pleaded not guilty to a 329 count indictment that includes multiple charges of kidnap and rape.
Gina DeJesus and Michelle Knight were in worse condition than Amanda Berry when they emerged from at least nine years in captivity at the home of Ariel Castro, sources told Reuters.
Castro, accused of their kidnap, appeared to treat Berry better than the other two, the sources added.
"There is a reason why you have only seen a picture of Amanda (Berry)," said one of the sources, referring to the condition of DeJesus and Knight.
"One of the girls has difficulty moving her head around from being chained up," said one of the sources. The second source identified DeJesus as the woman suffering this injury.
"It was like they were POWs (prisoners of war). They had bed sores from being left in positions for extended lengths of time," a source said.
Two of the women held captive in an Ohio house for almost a decade suffered from severe malnutrition and will require long-term therapy for injuries such as hearing loss and joint and muscle damage, Reuters reported, citing two sources with knowledge of the case.
The basement where the women were held had chains attached to the wall and dog leads attached to the ceiling, they claim.
The women were restrained with them and duct tape in "stress positions" for long periods that left them with bed sores and other injuries, according to the unnamed sources.
