Identifying Gunman in Manhattan Office Building Shooting: Shane Tamura
In the heart of New York City on July 29, 2025, a tragic event unfolded at 345 Park Avenue, Midtown Manhattan. The incident, perpetrated by Shane Devon Tamura, a 27-year-old man from Las Vegas, claimed the lives of four individuals and left one critically injured.
Tamura, who had a documented history of mental health struggles, entered a 44-story office building, armed with an AR-15 style rifle and wearing a bulletproof vest. The building, home to major financial companies such as Blackstone and the National Football League (NFL), was plunged into chaos.
The New York City Police Department swiftly responded, warning people to stay away from East 52nd Street between Park Avenue and Lexington Avenue. The situation quickly escalated, with many police cars blocking the streets and a helicopter flying above.
Commissioner Tisch confirmed that Tamura was found dead on the 33rd floor from a self-inflicted gunshot wound. The three other victims were two men and one woman, one of whom is in critical condition.
Tamura's car, with Nevada license plates, was found at the scene. Inside, police discovered a rifle case with bullets, a loaded revolver, magazines, a backpack, and medicine prescribed to Tamura. He shot a New York Police Department officer, a woman hiding behind a pillar, a security guard hiding behind a desk, and another man in the lobby.
Tamura, originally from Hawaii and later residing in Las Vegas, had a known history of mental health problems. He played high school football at Granada Hills Charter High School and Golden Valley High School in California, where he was a notable athlete, specifically a running back, earning multiple player-of-the-game awards and recognition for his performance during games.
In terms of work experience, Tamura worked as a casino security guard in Las Vegas. He held a concealed weapon permit in Nevada, obtained only weeks before the shooting, and also held a private investigator license. His legal record included a prior misdemeanor charge for trespassing.
Tamura's personal life appeared to involve living with his parents in Las Vegas before the attack. In 2022, there were at least two documented incidents where he was hospitalized for mental health crises. During one such event, his mother informed emergency dispatchers about his depression, concussion symptoms, use of sleeping pills and marijuana, and possession of a firearm.
Tamura reportedly traveled across the country from Las Vegas to New York City just before the attack, driving through several states before arriving at the location of the shooting. Surveillance footage showed him parking near the building shortly before the shooting began.
The attack, which Tamura carried out while referencing chronic traumatic encephalopathy (CTE) and accusing the football league of hiding concussion dangers, has left a profound impact on the city and the nation. Investigations into the exact motives behind the mass shooting continue.
- The tragic event at 345 Park Avenue, New York City, not only disrupted the general-news scene but also raised concerns about food safety, as several financial companies such as Blackstone and the NFL, home in the building, may have had perishable goods stored on site.
- Following the shooting, the New York City Police Department issued a health advisory, urging individuals to seek immediate medical attention if they had any knowledge of Tamura's prescribed medication or were previously treated by the same mental health professionals as him.
- While criminal charges have yet to be filed against Tamura posthumously due to his self-inflicted death, the sports community has been called into question as the shooter, an accomplished running back in his high school days, accused the football league of downplaying concussion dangers and linked his actions to chronic traumatic encephalopathy (CTE).
