A New York nurse has been charged in the killing of a developmentally disabled toddler who was submerged in scalding bath water.

Queens District Attorney Richard Brown says 54-year-old Oluyemisi Adebayo was arrested Wednesday just as she was about to board a flight to Africa.

Authorities say Adebayo was taking care of 23-month-old Naomi Mondesire on April 21 when she prepared her for a bath. Investigators say she told detectives she tested the water before placing Naomi in the tub. But she noticed skin falling off Naomi's legs when she took her out.

Police say Naomi was submerged in 130-degree water for 30 seconds. Naomi died Monday, three days after doctors performed surgery on her.

It's unclear if Adebayo has an attorney who could comment on the charges.
