Officials said the gunman fatally shot himself after his attack, which set off a chaotic scene that rippled out into the heart of Manhattan during rush hour.

A housekeeper on the 33rd floor made a split-second decision that saved her life, turning right as the Midtown gunman turned left and opened fire.

A man stalked through a Manhattan office tower firing a rifle, killing four people, including a New York City police officer, and wounding a fifth before taking his own life, officials said.
