A Brooklawn woman pleaded guilty to aggravated manslaughter yesterday in the 2006 killing of an infant, authorities said.
Gloria Carter, 37, faces up to 23 years in prison.
Carter appeared before Superior Court Judge Samuel Natal in Camden, where she admitted she sliced through the abdomen of her ex-boyfriend's child, 3-week-old Sean Colvin, on Nov. 18, 2006, and then threw the baby down a flight of stairs.
Carter was at the home of the child's father, Edward Colvin, on Chestnut Street in Brooklawn. Carter was not the mother.
