The NYPD and FBI have expanded their investigation into the devastating mass shooting at 345 Park Avenue in Midtown Manhattan, where four people were killed—including an off-duty NYPD officer—and another remains in critical condition. Authorities continue probing the shooter’s motives and potential connection to the building, which houses the NFL headquarters among other corporate offices.
What Happened
Incident Time & Location: On July 28 at approximately 6:28 p.m., a lone gunman identified as 27‑year‑old Shane Devon Tamura entered the lobby of 345 Park Avenue carrying an M4-style rifle, opened fire immediately, and killed multiple victims before taking his own life on the 33rd floor.
Victims Killed: Four individuals died, including NYPD Officer Didarul Islam, 36—a Bronx native working a private security detail. Also among the deceased was Wesley LePatner, a Blackstone executive, a security guard named Aland Etienne, and one other civilian .
Injured: At least one person remains hospitalized in critical condition. Several others sustained minor injuries while escaping the building .
The Shooter & Possible Motive

Mayor Eric Adams noted the note said: “You can’t go against the NFL—they’ll squash you.” .
Law Enforcement Response
NYPD Commissioner Jessica Tisch and FBI officials are leading the ongoing investigation. Secondary sweeps of the building have been conducted, and investigators are reviewing surveillance footage and electronic devices

Security protocols at the building were fragile but held firm, with safe rooms reportedly helping to limit casualties Building Lockdown: Offices including Blackstone, NFL headquarters, KPMG, and Rudin Management were affected. A large police presence—with drones and specialized units—secured the scene in the hours following the attack .
