Family, friends and members of the New York City Police Department will come together on Thursday for a funeral for the "hero" officer who was one of four people killed in the Midtown Manhattan mass shooting.

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 New York City police officer who was among the four people shot and killed by a gunman during a rampage at a Manhattan office tower will be laid to rest Thursday. Officer Didarul Islam, 36, was fatally shot Monday in a midtown building housing the National Football League’s headquarters.
