Manhattan Building Shooting: Who Was Gunman Shane Tamura?

Shane Tamura, identified as the gunman behind the deadly shooting at a Midtown Manhattan office building on Monday, July 28, 2025, was a 27-year-old man originally from Hawaii who later resided in Las Vegas, Nevada. The incident, which occurred at 345 Park Avenue—a high-rise housing prominent institutions like Blackstone, the National Football League, and the Irish Consulate—left five people dead, including a New York City police officer, before Tamura died from a self-inflicted gunshot wound.

Surveillance footage captured Tamura exiting a black BMW, armed with a .223-caliber Palmetto State Armory AR-15-style rifle. He immediately opened fire at the building’s entrance, shooting a uniformed officer before targeting a woman attempting to flee, a security guard, and another man inside the lobby. A loaded revolver, additional ammunition, and magazines were later discovered in his vehicle.

Authorities have indicated that Tamura had a documented history of mental health issues, although his specific motive for the attack remains unclear and is under investigation. A concealed carry permit, issued in Las Vegas in July 2022 and bearing Tamura’s photo, was found at the scene.

Unverified reports suggest Tamura was a former high school football player, having played as a running back at Granada Hills High School in California. A former teammate reportedly described him as a “goofball” and “class clown” who was full of energy. While some online theories speculate that a possible frustration over unfulfilled NFL aspirations might have played a role given the building’s tenants, law enforcement has not confirmed any link between his athletic history and the shooting.

The shooting triggered a massive emergency response, involving police, firefighters, and the FBI. The scene was quickly contained, and police confirmed that Tamura acted alone. The identities of the victims have not yet been publicly released as the investigation continues to piece together the full timeline and motivation behind this tragic event.
