New York City Mayor Eric Adams said at a Monday night press conference that there were three civilian deaths. Another male victim was seriously injured and "fighting for his life in a critical condition," he said.

He added that the police officer who died in the shooting was 36-year-old Didarul Islam, who served in NYC's 47th precinct and had started working less than four years ago.

In the presser, NYPD Commissioner Jessica Tisch said Islam was an immigrant from Bangladesh with two children and a pregnant wife.

"He made the ultimate sacrifice shot in cold blood, wearing a uniform that stood for the promise that he made to this city. He died as he lived, a hero," she said.

Responding to questions from journalists at the press conference, Tisch said the shooter, who police believed to be a 27-year-old man by the name of Shane Tamura, had a gun license in Nevada.

Tisch said the shooter had a Las Vegas address inside the vehicle he exited. She added that he had a documented mental health history.

"Inside of that vehicle, officers found a rifle case with rounds, a loaded revolver, ammunition of magazines, a backpack, and medication prescribed to Mr Tamura," she said.
