A mass shooting at a Manhattan skyscraper left four dead and several others injured after a heavily armed suspect opened fire in what officials say was a failed attempt to reach the NFL’s headquarters.
The shooter, identified as a 27-year-old man from Las Vegas, entered the lobby of the Park Avenue building with an assault-style rifle and began firing, killing a security officer and an NYPD officer assigned to the location. He then proceeded to an upper floor but mistakenly exited at the wrong level—bypassing his apparent intended target.
Authorities say the suspect had written a detailed note blaming the National Football League for his mental and neurological health issues. He claimed to have suffered lasting damage from playing high school football and believed the league was responsible for his condition. In his final writings, he requested that his brain be studied for signs of trauma.
Victims included a building security guard, a Blackstone executive, and a property management employee. The gunman ultimately took his own life inside an office suite after the attack.
Employees in the building barricaded themselves and called for help as the shooter moved through the floor. Law enforcement swiftly evacuated the premises, and the building remained closed through the next day as forensic teams conducted their investigation.
The FBI is working with local authorities to determine the origins of the shooter’s weapons and his travel path to New York. Reports indicate the suspect had previously been placed under mental health evaluations in another state. A detailed investigation is underway into whether others may have helped him acquire firearms.
The tragedy has prompted renewed concerns about building security, mental health monitoring, and the risks associated with unresolved personal grievances escalating into public violence. The NFL headquarters has suspended on-site operations while officials review protective protocols.
