A mass shooting on July 28, 2025, at the high‑rise office tower at 345 Park Avenue in Midtown Manhattan—home to Blackstone, the NFL, and KPMG—resulted in multiple fatalities and serious injuries. Authorities have confirmed the gunman was 27‑year‑old Shane Devon Tamura, who died by a self‑inflicted gunshot after killing four victims, including an off‑duty NYPD officer, and critically injuring one NFL employee.
Timeline of the Attack
- Around 6:30 p.m., Tamura arrived in Midtown from Las Vegas, driving a black BMW with Nevada plates. He entered the lobby armed with an M4 rifle, wearing a bulletproof vest and equipped with a silencer and scope.
- He immediately shot Officer Didarul Islam, a 36-year-old off-duty NYPD officer working security at the building. Three civilians were also fatally shot in the lobby.
- Tamura proceeded to the 33rd floor, where he killed another woman before turning the gun on himself.
