Gunman kills 4 in Manhattan skyscraper rampage before taking own life

A gunman armed with an assault-style rifle stormed a high-rise office building in Midtown Manhattan Monday evening, killing four people — including a police officer working security — before fatally shooting himself in a chilling attack that has stunned the city.

Authorities identified the attacker as 27-year-old Shane Tamura of Las Vegas, Nevada. According to police, Tamura entered the lobby of the skyscraper on Park Avenue around 6:30 p.m. ET, opened fire, and then took an elevator to the 33rd floor where he continued his deadly assault.

Among the victims was NYPD officer Didarul Islam, 36, who was on duty as a security guard in the building’s lobby. The identities of the other three victims — two men and one woman — have not yet been released, pending notification of next of kin.

“This was a horrific act of violence in the heart of our city,” said NYPD Commissioner Keechant Sewell at a late-night press briefing. “We believe the gunman acted alone and there is no further threat to the public.”

Initial investigations reveal Tamura drove cross-country from Las Vegas to New York. Law enforcement officials said he had a documented history of mental health issues, though his exact motive remains unclear.

Investigators are examining his digital footprint and questioning acquaintances to uncover any clues about the rampage.

The attack triggered panic in the densely populated commercial district. Witnesses reported scenes of chaos as the sound of gunfire sent pedestrians fleeing and workers barricading themselves inside offices.

“I heard five, maybe six shots, then screaming,” said Maya Rodriguez, an employee on the 32nd floor. “We pushed desks against the door and turned off the lights. We thought we were going to die.”

SWAT teams responded swiftly, evacuating the building floor by floor. Tamura was found dead from a self-inflicted gunshot wound on the 33rd floor, his weapon beside him.

New York Mayor Eric Adams called the attack “an unspeakable tragedy,” and praised the rapid response of law enforcement. “Officer Islam died doing what he had sworn to do — protecting others,” Adams said. “His heroism saved lives tonight.”

Federal and state officials have also joined the investigation, as the city reels from yet another mass shooting in the United States — a nation already grappling with the grim regularity of gun violence.

The skyscraper remains sealed off as authorities process the scene. Crisis counseling has been made available for employees and witnesses traumatized by the incident.

Officials say a full update will be provided once the identities of the remaining victims are confirmed and next of kin notified.
