A gunman opened fire inside a Manhattan skyscraper that houses the National Football League (NFL) headquarters and several major financial firms, killing four people before fatally shooting himself, New York officials confirmed on Monday evening.
Among those killed was off-duty NYPD officer Didarul Islam, an immigrant from Bangladesh, father of two, and soon-to-be father of a third child. Officer Islam had been working as a security guard at the time of the incident.
“He was a true blue hero,” said New York City Mayor Eric Adams, who praised Islam’s service and bravery during a press briefing.
Authorities provided limited details on the other victims, two men and one woman, whose identities have not yet been released. A fourth male victim remains in critical condition and is currently “fighting for his life” at a nearby hospital, according to the mayor.
New York City Police Commissioner Jessica Tisch confirmed that the suspect acted alone and was pronounced dead at the scene. “The lone shooter has been neutralized,” she said.
The gunman was identified as 27-year-old Shane Tamura, a Las Vegas resident with a known history of mental illness. Tisch stated that Tamura had driven cross-country to New York in the days leading up to the attack, stopping in Colorado, Nebraska, Iowa, and, most recently, New Jersey at 4:24 p.m. ET on the day of the shooting.
The incident began during evening rush hour in the lobby of the high-rise located at 345 Park Avenue in Midtown Manhattan. Surveillance footage captured Tamura exiting a double-parked black BMW between 51st and 52nd Streets before entering the building and opening fire.
Witness accounts and police reports indicate that Tamura shot several people upon entering the lobby.
He allowed one woman to exit the elevator unharmed before riding it to the 33rd floor, where he continued the shooting inside the offices of Rudin Management Company, a prominent New York real estate firm. One victim was killed on that floor.
Tamura then entered a stairwell and used an assault rifle to take his own life, Tisch said. Weapons and a prescription bearing Tamura’s name were recovered from his parked BMW outside the building.
Dramatic photographs showed dozens of people evacuating the building around 7:00 p.m. ET with their hands raised, as law enforcement secured the area.
The NYPD believes this to be an isolated incident with no additional threat to the public.
U.S. House Minority Leader Hakeem Jeffries issued a statement expressing his condolences: “May God watch over our city during this challenging moment,” he wrote, adding that he was “praying hard” for the fallen officer.
The skyscraper at 345 Park Avenue spans an entire city block and is home to the NFL’s corporate offices, investment firm Blackstone, and JP Morgan Chase.
Following the shooting, NFL employees were sent a security alert, according to ESPN reporter Jeff Darlington: “Do not exit the building. Secure your location and hide until law enforcement clears your floor. Please switch phones to silent.”
According to the Gun Violence Archive, a nonprofit organization tracking gun-related incidents, this marks the 254th mass shooting in the United States in 2025. The group defines a mass shooting as one in which four or more people, excluding the perpetrator, are shot or killed.
Witnesses near the scene described a chaotic aftermath. “I just saw a lot of commotion and cops and people screaming,” said Russ McGee, 31, who had been working out in a nearby gym when the shooting began.
Police investigations are ongoing.
