New York City was thrown into mourning and disbelief following a deadly shooting at a prominent Manhattan skyscraper on Monday. A man wielding an assault-style rifle opened fire inside the building, killing four people before fatally shooting himself.
The attack occurred in a tower known for housing the headquarters of the National Football League (NFL) and offices of major financial institutions. Authorities confirmed that the incident took place during working hours, sending panic through multiple floors as people scrambled for safety.

The identities of the victims have not yet been released, but officials say the fatalities include both office workers and visitors. Emergency responders arrived swiftly, evacuating the building and launching an investigation into how the gunman gained access.
Police believe the shooter acted alone and was not affiliated with any of the companies in the building. Surveillance footage and eyewitness statements are being reviewed to piece together his movements leading up to the attack.
As of Monday night, the motive behind the shooting remained unknown. Authorities are investigating the gunman’s background, possible grievances, and how he obtained the weapon. Mental health history and online activity are also being examined.
New York City Mayor Eric Adams condemned the violence and called for urgent reforms to curb gun violence in public and professional spaces.
