Four people were killed and a fifth was injured in a mass shooting at a Midtown Manhattan office building on Monday.

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.

The Bronx community met outside the 47th Precinct to honor the NYPD officer killed in the Midtown mass shooting. CBS News New York's Adi Guajardo reports.
