Mitchelle Blair stands during her video arraignment at the 36th District Court, Thursday, March 26, 2015, in Detroit. The Detroit woman charged with child abuse after the bodies of two of her children were found in her home freezer has been ordered to stay in jail Thursday unless she can post a $1 million bond.

DETROIT — A Detroit teenager says her mother killed two of her siblings and forced her to put one of their bodies in the freezer where they were found.

Child welfare workers say in a court filing that Mitchelle Blair's surviving daughter, who is 17 years old, said Blair tortured her 9-year-old brother, Stephen Berry, for about two weeks before he died in August 2012.

They say she told them her mother strangled her 13-year-old sister, Stoni Blair, in May 2013 after becoming enraged because Stoni said she didn't like her siblings. She said her mother made her put Stoni's body in the freezer.

The report says all of the children were severely abused.

Blair was arraigned on child abuse charges Thursday but could eventually face murder charges.
