AN APPEALS court in Brooklyn on Friday upheld the conviction for manslaughter and gun possession of a Long Island black man who shot a white teenager to death in a confrontation in front of the man’s home.

John H. White was sentenced to two to four years in prison for killing the teen, Daniel Cicciaro Jr., 17, who arrived at Mr. White’s house along with four other teens in two cars and challenged Mr. White’s son Aaron, 19, to fight as the group shouted racial epithets at the son and father, both of whom were armed.
