A gunman opened fire inside a high-rise corporate building in the heart of Manhattan on Monday evening, killing a New York City police officer and three other people, officials said.
The suspected shooter acted alone and died from a self-inflicted gunshot wound, law enforcement officials told NBC News.

The deadly gunfire, which was first reported about 6:30 p.m., was treated as an active shooting, prompting warnings and office evacuations, with lines of people seen leaving the building with their hands above their heads.
The gunman's motive has not been disclosed, though officials familiar with the investigation told NBC News that the suspect left a note at the scene voicing anger that his mental illness may be linked to his having played football.
Investigators are looking into whether that is a reason why he targeted the Park Avenue building, which houses the NFL's headquarters, the officials said.
Here's what we know so far:
The victims
A 36-year-old police officer who was expecting his third child was killed, officials said.
Didarul Islam, who emigrated to the United States from Bangladesh, had been with the NYPD for 3½ years, Mayor Eric Adams said. He was assigned to the 47th Precinct in the Bronx.
'He was doing what he does best and all members of the police department carry out,' Adams said. 'He was saving lives. He was protecting New Yorkers.'
Islam was the father of two young boys and was expecting a third child with wife, Police Commissioner Jessica Tisch said.
'He put himself in harm's way. He made the ultimate sacrifice — shot in cold blood, wearing a uniform that stood for the promise that he made to this city,' Tisch said, calling him a hero.
Three civilians also died. Their names have not been released. Another person was critically wounded.
Early Tuesday, the NFL, which has its headquarters in the office tower, said one of the league's employees had been wounded in the attack.
"One of our employees was seriously injured in this attack. He is currently in the hospital and in stable condition," NFL Commissioner Roger Goodell said in a statement to employees. "NFL staff are at the hospital and we are supporting his family."
He added that the football organization believed that all of its other employees were safe and accounted for.
"We are deeply grateful to the law enforcement officers who responded to this threat quickly and decisively and to Officer Islam, who gave his life to protect others," Goodell said.
The gunman
Law enforcement officials said the violence was carried out by a lone gunman, who died from a self-inflicted gunshot wound.
The suspect has been identified as Shane Devon Tamura, 27, of Las Vegas, according to four senior law enforcement officials.
In a photo three law enforcement officials shared with NBC News, the gunman is seen walking into the midtown Manhattan building wearing dark clothes and sunglasses and carrying what appears to be a large firearm.
A motive has not been determined but investigators are looking into the note left by the suspect, officials said.
The officials stressed that the investigation is early and ongoing.
In addition to the weapon and ammo, a cellphone was found at the scene and attempts would be made to get in it to see what it might contain, the officials said.
Caleb Clarke, a former classmate and high school football teammate, said Tamura 'was the biggest goofball in the world, just a ton of energy, class clown.' The two played together in California until Tamura transferred from a Santa Clarita high school to Grenada Hills High School in 2015, just before their senior year.
Clarke said that in recent years, he and Tamura kept up only through social media, where Tamura shared that he had been working at a casino in Las Vegas.
Clarke didn't recall Tamura ever being a troublemaker in school. 'You never would have thought violence was something you'd associate with him," Clarke said. "You know, he could make a joke about people, but that's just typical. Shane was a jokester. Everything he said was a joke. He had a ton of energy.'
He added that it seemed as if Tamura was destined for greatness as an athlete. 'I feel like it was definitely on the table for him,' Clarke said. 'I don't think he walked around to be like, 'Oh, I'll have NFL games one day.' I think it was more of everybody just telling him how great he was ... how special he was.'
The building
Midtown Manhattan's 345 Park Ave. is the headquarters of the investment firm Blackstone.
The building also hosts the headquarters of the NFL and a Bank of America branch, as well as offices belonging to KPMG.
Blackstone, Bank of America and the building's owner, Rudin Management, did not immediately respond to requests for comment.
In a statement, KPMG said its thoughts were with victims and their families.
'Our hearts go out to the victims of this horrific act and their families,' it said. 'We are incredibly grateful for the bravery of building security and law enforcement.'
CORRECTION (July 29, 2025, 2:11 a.m. ET): The headline in a previous version of this article misstated the last name of the suspected shooter. He is Shane Devon Tamura, not Temura.
