Mitchelle Blair, the Detroit mother who killed and put two of her children in a deep freezer in their apartment in March 2015, is facing new misconduct charges in prison, including the use of a Pringles can to fling urine and feces at guards.

Chris Gautz, public information officer for the Michigan Department of Corrections, said Blair is accused in two separate incidents. In the first one, he said, Blair allegedly put her urine and feces in a Pringles can and threw it in the face and chest of a corrections officer while they were trying to remove her food from a tray.

The second incident happened while Blair was being escorted down a segregation unit hallway. She began yelling at another prisoner, and as an officer attempted to stop the situation, Blair hit them in the arm and stomach.

Gautz said Blair has been taken out of the segregation unit and is back in general population.

Blair was sentenced Thursday for the two charges, where she will be serving two additional sentences of 38 months to five years.

WXYZ-TV reported that Blair has had 49 incidents since being taken to prison in 2015. However, Gautz said Blair has not been involved in any new incidents since December.

More:2 years after Detroit siblings found in freezer, abused kids have hope

Blair is serving a life sentence without parole at the Women's Huron Valley Correctional Facility in Ypsilanti in the murder of her children, Stephen Berry, 9, and Stoni Blair, 13.

The bodies of the children were found in a white freezer kept in the family's living room at the Martin Luther King Apartments by a crew carrying out an eviction notice on March 24, 2015. Blair is accused of killing Stephen in 2012, and Stoni in 2013. According to the Wayne County Medical Examiner's Office, Stephen died from multiple blunt trauma and thermal injuries and Stoni died of blunt trauma to the head.

Blair was accused of abusing all four of her children. She admitted she starved Stoni and threw scalding water on her, and told a judge she made Stephen drink Windex and put a bag over his head, causing him to lose consciousness.

The Free Press reported in 2017 that the oldest child, who was 19 at the time, was expected to graduate high school, with plans to go to college. Her then-10-year-old brother was also thriving in school and had been adopted.
