Police say Castro held Amanda Berry, 27, Gina DeJesus, 23, and Michelle Knight, 32, captive for more than a decade, repeatedly raping them until they were freed last Monday. Investigators say the three women were held against their will since going missing individually between 2002 and 2004.
In an exclusive interview with CNN, Pedro and Onil Castro showed no sympathy for their brother. They called him a "monster" and said they hope he spends the rest of his life in prison.
"I hope he rots in that jail. I don't even want them to take his life like that. I want him to suffer in that jail, to the last extent," said Onil Castro. "I don't care if they even feed him for what he has done to my life and my family's."
Pedro Castro said he feels the same way.
"If I knew that my brother was doing this ... I would call the cops because that ain't right," said Pedro Castro. "It's going to haunt me down, because people going to think, 'Yeah, Pedro got something to do with this,' and, 'Pedro don't have nothing to do with this.' If I knew, I would have reported it -- brother or no brother."
Last Thursday, police released Pedro and Onil Castro, saying neither man had anything to do with the alleged abductions and torture. Police say Ariel Castro, 52, kept the women chained in a basement and locked up in rooms.
According to DNA test results, Ariel Castro is the father of Berry's 6-year-old child, who was born in captivity. The girl was also rescued Monday after Berry was able to escape and cry out for help. Video surfaced over the weekend of the first moment the young women found their freedom.
"She kept holding the cop with her daughter ... and she was telling him, 'Keep me safe, keep me protected,'" said Ashley Colon, who took the video.
An imposing, 10-foot privacy fence will soon guard the home. Windows and doors are already boarded up. The rundown house has now become a two-story piece of evidence in the case. Neighbors say the house is just a terrible reminder and are calling for it to be torn down.
Ariel Castro has hired a private defense attorney. He remains jailed on $8 million bond and is under a suicide watch.
