Associated Press with video contributions from CNN Newsource - DETROIT (AP) - A 35-year-old Detroit mother faces arraignment in the slayings of two of her children whose bodies were found in a deep freezer.
A probable cause conference hearing also is scheduled Thursday for Mitchelle Blair.
Prosecutors charged Blair on Wednesday with felony murder, premeditated murder and torture.
Court officers carrying out a March 24 eviction at the family's apartment found the frozen corpses of 13-year-old Stoni Ann Blair and 9-year-old Stephen Gage Berry.
Blair initially was charged with child abuse, but more charges had been expected after autopsies revealed the siblings were beaten to death.
Investigators believe Stephen died in August 2012 and Stoni died the following May. Blair's two surviving children - ages 8 and 17 - have been placed into a relative's care.
Blair's defense attorney declined to comment Wednesday.
