NEW YORK — A shooting incident at a Manhattan skyscraper left four people dead, including a police officer who was working as a security guard. The shooter, who later took his own life, opened fire in the lobby of the 345 Park Avenue building, which houses the headquarters of several major corporations, including the NFL.

Didarul Islam, the slain officer, is remembered as a devoted family man, with his wife expecting their third child. New York Mayor Eric Adams honored him on Tuesday, calling him a “true blue hero.” While details regarding the other victims remain sparse, a third male was taken to a hospital in critical condition, fighting for his life, according to officials.

The lone gunman, identified as 27-year-old Shane Tamura from Las Vegas, had a documented history of mental health issues. Authorities indicated he had driven cross-country to New York shortly before the attack. Jessica Tisch, the police commissioner, confirmed that surveillance footage captured Tamura exiting a double-parked black BMW shortly before the shooting unfolded.

Witnesses described chaos as the incident occurred during the evening rush hour. “There was a lot of commotion—screaming and shouting,” said one bystander. Following the shooting, a heavy police presence enveloped the area, as law enforcement worked to secure the scene.

Local businesses advised employees to shelter in place amid the unfolding events. An NFL security alert instructed staff to remain indoors until the situation was under control. The building itself is known for housing vital corporate offices, including that of investment giant Blackstone and JP Morgan Chase.

The shooting highlights a persistent national concern, with the Gun Violence Archive recording this as the 254th mass shooting in the United States this year. This statistic reflects a grim reality of increasing gun violence affecting communities across the nation.

In the aftermath, President Joe Biden and House Minority Leader Hakeem Jeffries expressed their condolences, with Jeffries stating that his prayers go out to the families affected and to the NYPD. As investigations continue, authorities are focusing on the gunman’s background to understand the motivations behind this tragic incident.
