Barzee has pleaded guilty to federal charges, but has not yet been sentenced. She is confined to a mental hospital while awaiting state charges in the Smart case. Mitchell has not yet been tried.
Barzee's children either left home or were thrown out of the house by the time they were 13 or 14, they told Oprah.
Gayler said she left after the rabbit dinner, but it was the "last straw" after years of abuse. She wasn't allowed to watch any television except National Geographic programs and was made to kneel and pray for two or four hours a day.
She recalled one disturbing prayer session.
"My mom was praying and I was kneeling there, and Brian actually nudged me and he pulled out some photos of some nude women and laid them up on the bed, and it seems that they were trying to get me to participate with them that day," she said.
Gayler remembered a toy kitchen she was given as a little girl. "It was one of my favorite things," she said. One day she came home and it was gone, and her mother "got a sense of happiness about it. She had a smirk," Gayler said.
Rhonda McLeod, the oldest of Barzee's children, said she had the closest relationship with her mother and keeps in touch with her by mail.
"I've told her that I've forgiven her," McLeod said. She read part of a recent letter from Barzee in which Barzee said all of her children were "precious" to her.
Gayler shook her head and said the letter "kind of makes me sick."
When asked what punishment they believe their mother deserves, Andrea said her mother should be put away.
"I don't think she should see the light of day again," she said.
Barzee issued a statement to the show through her lawyer saying she couldn't comment because of her upcoming trial, but said she hopes to continue to repair relationships despite her "serious and unique circumstances."
