The last killing of such a scale in the city was during a fast-food restaurant robbery in Queens in 2000. Mass murders of strangers are rare.

Mayor Eric Adams on X: "Tonight, our city is reeling and four innocent families are mourning, including the family of NYPD Officer Didarul Islam, who was killed at 345 Park Avenue. He represented the best of New York City, an immigrant from Bangladesh who put on a uniform to protect and serve us all."
