DETROIT — A Detroit woman pleaded guilty Monday to killing two of her children and storing their bodies in a home freezer.

Mitchelle Blair, 36, has never challenged allegations that she killed her 13-year-old daughter and 9 year-old son, even saying she would accept the death penalty if Michigan had it. She faces life in prison with no chance for parole.

She was arrested in March, after deputies carrying out an eviction at her Detroit apartment found the bodies of her daughter, Stoni Blair, and son, Stephen Berry, in a deep freezer.

"I don't regret none of this," Blair told the judge Monday. "I don't feel no remorse for the death of those demons."

Blair said she beat and suffocated the kids months apart in 2012 and 2014. She said she intended to kill Stoni, but didn't know that the attacks on Stephen would kill him.

Mental health experts had previously found Blair competent to face charges. She was charged with murder, torture and child abuse.

In a separate case, authorities are seeking to end Blair's parental rights to her other two children, ages 8 and 17. 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.

During hearings in that case, Blair also declared her guilt to the deaths during outbursts in court. A videotape played during a hearing this month showed her surviving son telling a social worker that he was whipped with a cord and that his sister was hit with a hammer.
