A Manhattan mother has been arraigned in connection with the fatal stabbing of her son.
Yvonne Hines, 52, pleaded not guilty to a manslaughter charge and is being held without bail.
Sean Hines, 18, was found just before 11 p.m. Friday inside his family's apartment on West 92nd Street. He had been stabbed in the leg.
The stepfather of Sean Hines was questioned but was not charged.
Sources say Sean Hines and his mother were arrested for assault during the summer, and his mother had been accused of child abuse.
