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

A shooting Monday at an office building in New York City that is home to the Blackstone investment firm and the NFL left four people dead, including an NYPD officer.

Familly, friends and colleagues are preparing to mourn the NYPD officer killed in this week’s Manhattan office attack at a funeral Thursday, less than two days after hundreds stood in salute as his casket received a dignified transfer to the mosque where he’ll be remembered.
