Gunman Kills Four, Including NYPD Officer, in Manhattan Office Tower Shooting Before Taking His Own Life

New York Police Department (NYPD) officers are seen as they respond to an incident in the Midtown Manhattan neighborhood of New York on July 28, 2025. Police are investigating an "active shooter" incident, New York Mayor Eric Adams said on X (formerly Twitter) with the NYPD advising residents to "avoid the vicinity of East 52 Street between Park Avenue and Lexington Avenue"

A gunman opened fire inside a Manhattan office skyscraper Monday evening, killing four people—including a New York City police officer—and seriously wounding another before taking his own life, according to authorities.

The deadly rampage unfolded around 6:30 p.m. at 345 Park Avenue, a high-rise in Midtown Manhattan that houses the headquarters of the NFL, investment giant Blackstone, financial services firm KPMG, and real estate company Rudin Management.

Authorities identified the shooter as Shane Tamura of Las Vegas, a man with a documented history of mental illness. While his motive remains unclear, NYPD Commissioner Jessica Tisch stated, “We are working to understand why he targeted this particular location.”

Security footage showed Tamura exiting a double-parked BMW with an M4 rifle and walking calmly across a public plaza into the lobby before opening fire. He first shot and killed Officer Didarul Islam, a 36-year-old NYPD officer assigned to a corporate security detail. Islam, an immigrant from Bangladesh, had served on the force for over three years and leaves behind two sons and a pregnant wife. “He died as he lived—a hero,” Tisch said.

Tamura then shot a woman who attempted to take cover as he sprayed the lobby with gunfire. He proceeded to the elevator bank where he fatally shot a security guard and another man in the lobby before ascending to the 33rd floor—home to Rudin Management’s offices—where he killed another victim before turning the gun on himself.

One man remains in critical condition, while four others suffered minor injuries while fleeing the scene. Mayor Eric Adams stated, “We are still unraveling what took place,” as officials continued to gather evidence and speak with witnesses.

Inside Tamura’s car, police recovered a rifle case, a revolver, magazines, ammunition, and prescription medication. His travel history shows he drove cross-country, passing through Colorado, Nebraska, Iowa, and arriving in New York just hours before the shooting.

The skyscraper is located in a busy corridor of Midtown, just north of Grand Central Terminal and one block from St. Patrick’s Cathedral. The location is a major hub for both business and tourism, raising concerns about security in corporate spaces.

Witnesses described scenes of chaos and fear. Nekeisha Lewis, dining nearby, recalled hearing “a quick two shots and then rapid fire.” She saw windows shatter and a wounded man screaming for help. Jessica Chen, attending a meeting on the second floor, said she and colleagues barricaded themselves in a room. “We were honestly really, really scared,” she said, texting her parents goodbye.

The building was evacuated as officers swept through each floor. Crowds of workers, many with hands raised, were seen leaving in waves. Some employees took shelter in nearby buildings for hours before being allowed to go home.

Commissioner Tisch noted that Tamura had no known connections to Rudin Management or the real estate industry, and no prior link to New York City. Investigators are combing through evidence to determine if there was a broader agenda or if the attack was random.

This tragedy comes as New York City remains on track for one of its lowest homicide and gun injury rates in decades. However, it follows recent corporate-related violence, including the high-profile killing of UnitedHealthcare CEO Brian Thompson last December—another incident that rattled the business community.

Tamura’s deadly actions have once again placed mental health, gun violence, and corporate security under urgent scrutiny in one of the world’s busiest business districts.
