A mother who killed two of her children and kept them in the freezer 'doesn't regret a thing'.

Trigger warning: This post discusses child abuse in detail.

To the outside world, Mitchelle Blair was a single mother of four doing her best to make ends meet.

No one could possibly know the horrors hidden in the living room of her Detroit townhouse.

When people questioned the 36-year-old on the whereabouts of her 13-year-old daughter, Stoni Blair, and nine-year-old son, Stephen Berry, she said they were living with their aunt.

She told local public schools she had withdrawn her kids because the family was moving interstate.

She continued to collect welfare payments for them.

But Stoni and Stephen weren’t living with their aunt. They were dead. Killed nine months apart at the hands of their trusted mother and stuffed into a deep freezer in the living room.

Blair killed her third born, Stephen, on August 30, 2012 – telling police after she was arrested in March this year that he was in the freezer for, “I wanna say two years”.

On her daughter: “She has been in there about one year.”

Stoni was murdered on May 25, 2013.

Blair’s two surviving children, an 8-year-old boy and a 17-year-old daughter, knew about their siblings in the freezer.

But it wasn’t until authorities tried to evict the family from their home in March this year that they discovered the bodies of her two middle children in the living room freezer.

Blair was arrested and her two surviving children were shipped off to relatives.

All four children had been horrifically abused.

Blair told a judge she didn’t mean to kill her son, but intentionally killed her daughter and didn’t “regret any of it”, Detroit Free Press reports.

“I don’t feel no remorse for the death of them demons.”

She admitted punching her daughter, putting a bag over her head until she lost consciousness, throwing scalding water on her and repeatedly hitting her on the head “over and over”.

“I definitely meant to kill her,” she said.

“If I had a chance to do it again, I would.”

Nine months earlier, she fatally assaulted her son Stephen, making him drink Windex, burning his genitals with hot water and putting a belt around his neck, lifting him up with it until he lost consciousness.

She said she wrapped his body in his favourite Paul Frank comforter, with monkeys on it, and stuffed him into the deep freezer.

Nine months later, she forced her eldest child to put her sister’s lifeless body in the same freezer, on top of her dead brother.

She told police she showed both surviving children the bodies of their siblings. She said her daughter cried a lot, while her eight-year-old son looked at her and said, “You’re going to be in trouble”.

In an almost unprecedented move, Blair pleaded guilty to the first-degree murder of Stoni without any deal with prosecutors and to the felony murder of Stephen. She said she would have accepted the death penalty if Michigan had it.

She claimed the two children had been abusing one of their siblings.

Blair – who now faces life in prison with no chance of parole when she is sentenced next week – has been found fit to face the charges by mental health experts.

When the Detroit community learned of the siblings’ deaths, they placed flowers, stuffed toys and notes alongside a baseball bat and other childhood items casually strewn outside the home that guarded the horrible secret for so long.

A home that, to the outside world, looked just like any other.
