DETROIT -- A Detroit woman pleaded guilty Monday to killing two of her children and storing their bodies in a home freezer, telling a judge that she had no remorse for beating and suffocating them.

Mitchelle Blair, 36, has never challenged allegations that she killed her 13-year-old daughter and 9 year-old son. She pleaded guilty to first-degree murder without any deal with prosecutors - an extraordinary move - and said she would have accepted the death penalty if Michigan had it.

She was arrested in March, after deputies carrying out an eviction at her Detroit apartment found the bodies of her children in a deep freezer. She said she attacked the children months apart in 2012 and 2013.

Blair said she intended to kill her daughter, Stoni Blair, but didn't know the abuse of her son, Stephen Berry, would be fatal. Blair alleged the children had sexually abused a sibling, though she said she didn't witness the alleged assaults and didn't get police involved because she feared she would lose her other children.

"I don't regret none of this," Blair told Judge Dana Hathaway during the hearing. "I don't feel no remorse for the death of those demons."

Mental health experts had found Blair competent to face charges. She faces life in prison with no chance for parole.

Hathaway asked a series of questions about what happened. Blair said she repeatedly beat Stoni and Stephen, and poured scalding water on them. She said she made Stephen drink window cleaner.

"So this was your way of inflicting punishment?" the judge asked.

"Definitely," Blair replied in a matter-of-fact tone.

At the request of prosecutors, Hathaway asked Blair if she had ever called police about the alleged sexual assaults. Blair said she called police with a "hypothetical" situation, seeking to know if other children in the home would be removed if she reported the assaults.

In a separate case, authorities are seeking to end Blair's parental rights to her other two children, although the guilty plea should guarantee it. A videotape played during a hearing this month showed her 8-year-old son telling a social worker that he was whipped with a cord and that his 17-year-old sister was hit with a hammer.

The state also wants to end the parental rights of their fathers, saying the men rarely see the children and owe thousands of dollars in child support.

She asked for it and got it. Mitchelle Blair will spend her life in prison with no chance of parole for murdering two of her children and hiding their bodies in a freezer.

Blair lashed out at the fathers of her surviving children and their families during Friday's sentencing.

"You imposed the death penalty on your own children," Judge Dana Hathaway said in court.

"I did," Blair said.

The Detroit mother who admitted to killing her two children, 9-year-old Stephen Berry and 13-year-old Stoni Blair and hiding their bodies in a freezer, accepted her fate.

"The greatest tragedy here is that they will never know what a life is like without experiencing fearing their mother."

Blair, who says she was physically and sexually abused as a child, continues to say she killed Stoni and Stephen because they were sexually assaulting her two surviving children.

"There is no evidence in this case," said Carin Goldfarb, assistant Wayne County prosecutor. "That any of the younger children or the younger child was sexually abused."

"How dare you, say nothing happened to my son," Blair said in court. "You weren't there. You all were never there."

Reading a victim impact letter, Blair was able to make statement as well, focused on her children's absent fathers Alexander Dorsey and Steven Berry, who are trying to regain custody of their two surviving kids.

"They want to talk about how they love my daughters," Blair said. "Now they want to be front and center but they were always in the background. They never did anything for them. They never showed up to my door once."

One of the fathers was seen smiling as Blair stood before judge Hathaway.

"How do you smile when your two children have been killed," said defense attorney Wyatt Harris. "I could see nothing to smile about."

Although Blair accepts responsibility for actions, her anger and lack of remorse overshadows the sincerity.

As she was led out of the room, she flashed middle fingers at the fathers.

Wayne County Prosecutor Kym Worthy said on Friday that the situation is simply all around tragic.

In a statement she said:

"There were no winners - only losers. I truly hope these children can finally rest in peace."

While Mitchelle Blair's criminal trial is now over, the custody over her two surviving children continues. Both fathers were ordered to undergo psychological evaluations. That hearing resumes July 27.
