WEEHAWKEN, N.J. -- Officials believe the mother who left her battered newborn on the steps of a New Jersey high school is a teacher in a neighboring school district.

West New York School Superintendent John Fauta says the 37-year-old has taught math to special education students at West New York's Memorial High School since 2007.

The woman, whose name has not been released, is undergoing a psychological evaluation and has not been charged.

The 1-month-old girl was wearing only a diaper and wrapped in a blanket when a parent found her at Weehawken High School on Friday.

Prosecutors say the baby is being treated for multiple fractures, including a skull fracture.

Fauta told The Journal of Jersey City his concern is not only for the child, but that the mother gets proper treatment.
