She was visiting the sixth floor apartment of a friend and was killed after getting into an argument with the friend’s ex, sources told 1010 WINS’ Roger Stern.

Friends and neighbors are grief stricken and angry.

“What I know is my sister-in-law is dead and somebody have to pay for it,” the victim’s sister-in-law Joni Gary-Smith said.
