Police arrested the mother Tuesday after the gruesome discovery was made that morning. A bailiff was at the house to evict the woman. She was not inside when the bailiff was there. While in the home, the bailiff found the bodies of an 11-year-old boy and a 14-year-old girl inside a freezer.
Mitchelle Blair, 35, admits to killing her two kids and then hiding their bodies in her freezer. 13-year-old Stoni Ann Blair and 9-year-old Stephen Gage Berry were found dead inside a freezer in the townhome on the east side of Detroit. Stoni would be 15 today, Stephen would be 11.
Outside the home on Wednesday, messages of love and prayers were left for the two young children while neighbors say she was living a lie.
On Wednesday, a police source told FOX 2's Erika Erickson that the children were trying to sexually assault their younger brother.
According to the same source, the mother told them "I am not evil. It was just an evil act".
The now 8-year-old boy and his 17-year-old sister are both now in protective custody. Friends say the children may have known what Blair had done but were too afraid to say anything.
Sources say Blair pulled her children out of school years ago because she wanted to home school them. She reportedly told family and friends, who hadn't seen Stoni or Stephen in awhile, that they were "doing mean things" to their younger brother like taking his food and "raping him," so she sent them away.
Blair, according to sources, says she confronted Stephen in August of 2012 and he admitted to the sexual acts. That's when sources say she put the then 9-year-old in scalding water, resulting in his death. The source said she wrapped him in his "favorite blanket," and put him in the freezer.
Just 9 months later, in May 2013, sources say Blair discovered Stoni sexually assaulting the younger brother. She snapped. Sources say Blair admits to starving and abusing Stoni for a week before strangling her with a shirt and suffocating her. Then she wrapped her in a garbage bag and placed her on top of Stephen, the source said.
On Wednesday, Blair was charged with four counts of child abuse and one count of committing child abuse in the presence of another felony. She faces life in prison. She'll be arraigned Thursday morning.
Meanwhile, outside the house of horrors, neighbors and friends remain in shock about what was happening inside.
