On the evening of July 28, 2025, a disturbing mass shooting unfolded at 345 Park Avenue, a 44‑story office tower in Midtown Manhattan. The building, located between East 51st and 52nd Streets, houses major tenants such as Blackstone, KPMG, Deutsche Bank, and the National Football League (NFL) headquarters.
⏱ Timeline of the Attack
Shortly before 6:30 p.m. EST, surveillance footage captured a man, later identified as 27‑year‑old Shane Devon Tamura, double parking a black BMW in front of the building. He exited the vehicle carrying a Palmetto State Armory AR‑15‑style M4 rifle, began firing in the lobby, and launched what authorities described as a spree of “automatic‑style gunfire”.
Inside the lobby, Tamura first shot an off‑duty NYPD officer, Didarul Islam, who was working a paid security detail. He then fired at a woman who had attempted to take shelter behind a lobby pillar, sprayed bullets across the area, and shot a security guard taking cover behind the desk. A male bystander was also wounded during the chaos.
Tamura then boarded an elevator and rode to the 33rd floor, home to Rudin Management Company. From there, he fatally shot another individual before turning the gun on himself in a hallway. Emergency responders and police secured the scene within minutes. Tamura was pronounced dead from a self‑inflicted gunshot wound.
📊 Casualties and Victims
In total, five people died in the incident:
- Didarul Islam, age 36, the NYPD officer who made the ultimate sacrifice.
- Three office workers — two women and a man — killed in the lobby and on the 33rd floor.
- Shane Tamura, the attacker, who died by suicide.
Another male victim, believed to be an NFL employee, sustained serious injuries and remains in critical but stable condition. Several others escaped with minor injuries amid frantic evacuations.
Officer Islam, a Bronx precinct officer, was described as a devoted public servant: he had nearly four years of service, two young sons, and a third child on the way. He was hailed as a hero by both NYPD and city leadership.
🧠 The Shooter: Profile and Possible Motive
Shane Devon Tamura, originally from Las Vegas, had no significant criminal history. However, he held a Nevada concealed-carry firearms permit, issued in June 2022 and valid for five years, and briefly held a private investigator license. Police also found prescribed medication in his vehicle.
According to police statements, Tamura drove across the country from Las Vegas, traveling through Colorado, Nebraska, Iowa, and arriving in New Jersey just minutes before entering New York City. At the scene, officers discovered multiple weapons, ammunition, a rifle case, and his backpack, though no explosives.
Authorities described Tamura as having a documented history of mental health issues, but investigators have yet to confirm whether this played a direct role. No clear motive or connection to the building or its tenants has been established.
🚨 Police Response and City Aftermath
The NYPD declared the location secure shortly after the shooting; law enforcement, including SWAT teams, counter‑terrorism, and bomb squad units, were deployed to contain the incident. The FBI’s New York field office also joined the investigation.
New York City Mayor Eric Adams condemned the tragedy, describing it as an “act of evil” and extending his deepest sympathies to the bereaved families. Police Commissioner Jessica Tisch praised Officer Islam’s bravery and reaffirmed that authorities were working to understand why Tamura targeted this specific building.
