Teenage girl 'stabs brother to death in fight over cellphone'... after calling 911 to warn she was about to kill him

A teenager in Queens, New York has been arrested after allegedly stabbing her brother to death in an argument over a cellphone. Neighbors heard screams from the first-floor Woodhaven apartment after a fight broke out between Yocairis Diaz, 18, and Frank Fortuna, 20, on Friday afternoon. Diaz called 911 and told the operator: 'If you don't get here fast, I'm going to kill this guy!' Moment later, a neighbor heard another brother Kelvin Diaz, 19, yelling: 'Help me, help me! He’s dying!'. 'Frankie was lying on the ground bleeding and his eyes were rolling back in his head,' the neighbor told The New York Post.
