Mount Vernon police have charged the mother of two children who wandered away from their home last week.
The two girls, ages 2 and 4, were found at Benjamin Turner Middle School on Thursday.
Police say the two opened their front door and walked out of their home, located across the street from the school.
The mother, 36-year-old Monica Fairbanks, has been charged with endangering the welfare of a child.
The girls are now staying with their father.
