Midtown Manhattan Shooting: Gunman Shane Tamura Opens Fire Inside 345 Park Avenue
On the evening of Monday, July 28, 2025, a gunman armed with an AR‑15‑style rifle stormed into the lobby of the 44‑storey office tower at 345 Park Avenue in Manhattan. Over the following minutes, he killed four people—including an off‑duty New York City police officer, and wounded others before turning the weapon on himself.
How the Attack Unfolded
Around 6:30 p.m. ET, passionless surveillance footage shows 27‑year‑old Shane Tamura stepping out of a double‑parked BMW while carrying a rifle. He calmly walked into the building lobby and opened fire.
Tamura first shot the off‑duty NYPD officer, Didarul Islam, who was on a security detail, then began firing indiscriminately, targeting a woman hiding behind a pillar, a security guard at a desk, and other civilians in the lobby.
He then proceeded to the 33rd floor, home to Rudin Management, where he killed another person before committing suicide.
Victims and Casualties
A total of four people died, including Officer Didarul Islam, aged 36, a father of two whose third child was on the way. Citizens in nearby offices suffered minor injuries while one person remains critically wounded.
The gunman also died from a self-inflicted gunshot wound.
Chaos, Fear, and Firsthand Accounts
Witnesses described scenes of horror, calling it a “war zone” as frightened employees barricaded themselves using office chairs, desks, and tables. Workspaces went into lockdown, and nearby buildings issued “shelter-in-place” alerts.
One attendee, Jessica Chen, remembered: “We heard multiple shots in quick succession… we barricaded the doors with tables and stayed silent.” Others said they texted loved ones in panic as gunfire echoed.
Who Was Shane Tamura?
Identified as a 27‑year‑old man from Las Vegas, Tamura had a valid Nevada concealed‑carry permit, dated June 2022, and reportedly a history of mental health struggles.
His vehicle traced a multi‐state journey through Colorado, Nebraska, Iowa, and New Jersey before reaching New York earlier the same day. Investigators discovered a rifle case, a revolver, ammunition, and prescription medication inside.
Investigation & Official Response
Police confirmed Tamura acted alone, with no immediate links to extremist activity. A detailed motive remains unestablished.
NYPD Commissioner Jessica Tisch stated investigators are probing why 345 Park Avenue was targeted. The building houses major tenants including Blackstone, KPMG, the NFL headquarters, and the Irish consulate.
New York City Mayor Eric Adams praised Officer Islam as “a hero, a true‑blue New Yorker” and extended condolences to all victims.
The FBI joined local law enforcement to assist in the widened investigation.
