MONTGOMERY COUNTY, MD (CNN) - Police say a Maryland mother stabbed two of her children to death and wounded two others while attempting an exorcism.
Zakieya Avery, 28, was charged Saturday with two counts of first-degree murder and two counts of attempted first-degree murder.
A second woman who police say lived in the same home was also charged in the deaths of Zyana Harris, 2, and her 1-year-old brother Norell.
Police say they found the children Friday morning after a neighbor called 911 to report suspicious activity at the Germantown home.
Investigators say the two accused believed they were performing an exorcism.
