A Detroit woman has pleaded guilty to killing two of her children and storing their bodies in a home freezer.

Mitchelle Blair has never challenged the allegations. She entered her plea to murder Monday, saying she killed her 13-year-old daughter and 9-year-old son months apart.

She faces life in prison without parole.

The children's bodies were discovered in a freezer in March, while Blair was being evicted from her Detroit home. Police believe they died in 2012 and 2013.

For weeks, the 36-year-old Blair has openly declared her guilt and even said she would accept the death penalty if Michigan had it.

Authorities also are seeking to end her parental rights to two other children.
