On Monday evening, July 28, 2025, a lone gunman stormed into 345 Park Avenue, a high‑rise in Midtown Manhattan that houses major tenants like the NFL headquarters, Blackstone, KPMG, and Rudin Management, and opened fire with a rifle in the lobby and on the 33rd floor. He killed four people, including NYPD officer Didarul Islam, and seriously wounded one person before turning the gun on himself.
Authorities named Shane Devon Tamura, 27, of Las Vegas who had a known history of mental health struggles as the gunman. Tamura drove cross‑country, traveling through Colorado, Nebraska, Iowa and New Jersey before arriving in New York just before the attack
Authorities say he entered the building wearing a bulletproof vest and armed with an M4 assault rifle. Surveillance footage showed him exiting a double‑parked black BMW near Park Avenue around 6:30 pm, marching across a plaza, then opening fire immediately after entering the lobby.
In the lobby, Tamura shot Officer Islam who was on duty under a private detail program then struck a woman and a security guard before moving toward the elevator bank. He then rode the elevator to the 33rd floor, where he killed another person associated with Rudin Management. He shot himself in the chest, ending the rampage
Officer Didarul Islam, 36, was an immigrant from Bangladesh and had served with the NYPD for about three and a half years. He leaves behind two young sons, and his wife is pregnant with their third child. Commissioner Jessica Tisch and Mayor Eric Adams honored him for bravely giving his life in the line of duty to protect others.
A fifth victim remains hospitalized in critical condition. Three other individuals suffered minor injuries while fleeing the building. The NFL confirmed that one of its staff members sustained serious injuries and is now in stable condition. The league issued a memo expressing gratitude to law enforcement and offering support to employees, including remote work options during the building’s closure.
Police Commissioner Tisch said investigators have not yet determined a motive. Tamura left writings indicating he believed he had chronic traumatic encephalopathy (CTE) and held grievances against the NFL for neglecting individuals affected by the condition. Officials are reviewing whether the NFL-related beliefs influenced his actions
New York City leaders called for calm, assuring the public that the building and surrounding area are secure. Law enforcement agencies including the FBI remain on the scene as the investigation continues.
