During evening rush hour in New York City on Monday, a man calmly walked into a Park Avenue office building lobby and killed a police officer, then opened fire on other innocent strangers.

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.

The shooting occurred in the lobby of 345 Park Avenue on East 52nd Street, an office building that records indicate is home to the NFL, Blackstone and KPMG.
