Police officer among 4 killed in Manhattan skyscraper shooting

On Monday evening, Monday (28), a gunman armed with an assault-style rifle opened fire inside a skyscraper at 345 Park Avenue, Manhattan’s Midtown district. The attack left four people dead—including New York City police officer Didarul Islam—and one critically injured before the suspect took his own life. The attacker, identified as 27-year-old Shane Tamura from Las Vegas, carried out a deadly shooting spree inside a building that hosts major tenants such as the National Football League (NFL), Blackstone, KPMG, and other financial firms.

Sequence of events

Tamura entered the office building's lobby at around 6:30 p.m. ET, armed with an M4-style rifle. Surveillance footage showed him walking in carrying the weapon. He first shot and killed Officer Didarul Islam, who was providing security at the time.

The gunman then fired indiscriminately in the lobby, wounding a woman who hid behind a pillar, a security guard seated at a desk, and another man. He proceeded to the elevator and traveled up to the 33rd floor. There, he fatally shot another individual in the offices of Rudin Management, the building’s landlord. Ultimately, Tamura fatally shot himself in the chest in a hallway on that floor.

Heroic officer Didarul Islam

Officer Didarul Islam, 36, was a Bangladeshi immigrant and NYPD officer for three and a half years. He is remembered as a hero who sacrificed his life protecting others. Islam leaves behind a wife, two young children, and a third child on the way. New York City Police Commissioner Jessica Tisch praised him, saying, "He made the ultimate sacrifice" while serving the job asked of him.

Suspect’s background and motive

Police revealed Shane Tamura had a history of mental health issues and reportedly drove all the way from Las Vegas to New York. Authorities found a note at the scene suggesting Tamura believed he suffered from chronic traumatic encephalopathy (CTE), a brain condition often linked to repeated head injuries, notably in football players. Tamura himself played high school football in California. The note contained vague references to the NFL, raising speculation about his motive, though the investigation is ongoing.

Aftermath and police response

The shooting plunged parts of Midtown Manhattan into chaos. Streets and public transit services were temporarily halted, and buildings nearby underwent evacuations and lockdowns. Pedestrians fled in panic as gunshots echoed through the area. Police conducted a floor-by-floor clearing operation that lasted several hours. Emergency medical personnel treated the wounded, including an NFL employee who was seriously injured but stabilized.

FBI Deputy Director Dan Bongino confirmed federal agents were assisting the NYPD. Mayor Eric Adams and other officials condemned the violence and expressed condolences to the victims’ families.

The Monday (28) shooting at a Manhattan office building resulted in four deaths—including a revered NYPD officer—and serious injuries, before the gunman ended his own life. Motivated possibly by mental health challenges and a link to football-related brain injury concerns, the shooting has shocked New Yorkers and drawn national attention. Authorities continue their investigation to fully understand the motives and circumstances surrounding the attack.
