A gunman seen carrying an M4 assault rifle killed four people, including one police officer, when he opened fire in broad daylight in the heart of New York City, before he reportedly took his own life.
In terrifying security camera photos, the gunman could be seen casually strolling into a midtown Manhattan office building on Monday wearing a sport coat and button-down shirt while carrying the large rifle.
The gunman was identified as 27-year-old Shane Tamura from Las Vegas.
He was a former high school football player with a history of mental health issues. The gunman traveled across the country before the shooting, according to NYPD Commissioner Jessica Tisch.
The building houses Blackstone asset management and the NFL.
Tamura had a silencer on his rifle when he opened fire inside the lobby at around 6.30pm, according to CNN. The firearm also had a scope and strap.
Officer Didarul Islam, who was working private security at the time, was shot and killed in the lobby of the building. One other shooting victim was fighting for their life on Monday night.
Meanwhile, the gunman was found dead from a self-inflicted gunshot wound on the 33rd floor of the building, where Blackstone has its headquarters.

During a press conference on Monday night, Commissioner Tisch gave more details about the tragedy while emphasizing the city was safe from the gunman's terror.
'I want to be very clear, we believe this to be a lone shooter, and there is no longer an active threat to the public,” the commissioner said.
The mayhem started when Tamura entered the lobby of the building at 365 Park Avenue wielding the assault rifle before opening fire on NYPD Officer Islam and three others.
The gunman then proceeded to the elevator bank where he shot a security guard before allowing a female to walk out of an elevator before riding up to the 33rd floor.
When he arrive on the floor he opened fire on at least one other person before turning the weapon on himself.
Videos shared online showed officers in protective gear entering the building with their guns drawn.
Another video taken by Fox 5 showed several officers carrying a victim, while others appeared to be tending to a person lying on the ground.
Islam, the officer, emigrated from Bangladesh. He was the father of two young boys. His wife is eight months pregnant with their third child.
EMS First shared a tribute to Officer Islam following the news.
'Tonight, a chair at the dinner table is left empty. Tonight, a family grieves a loss that cannot be measured. Tonight, a hero made the ultimate, selfless sacrifice in the line of duty,' it wrote on Instagram.

A witness told The New York Post that 'it sounded like a barrage of shots …Like an automatic weapon. Like a high-capacity weapon.'
Another person told the paper that a 'guy came in with an assault rifle and started shooting.'

Sources told NBC News that investigators were probing whether he may have been targeting the NFL offices.
He started the rampage in the lobby of the office building where he first exchanged gunfire with the NYPD Officer Islam, according to CNN.
