At least five people, including a police officer, were killed in a shooting inside a high-rise office building in central Manhattan, New York, on Monday evening. The incident took place at 6:00 pm local time, after police received reports of gunfire near Park Avenue, a busy area frequented by tourists and business travellers. Shane Tamura, 27, was found with a letter referencing grievances against the NFL, particularly its handling of chronic traumatic encephalopathy (CTE), a degenerative brain disease linked to repeated head trauma in former football players

What was the mistake that Shane Tamura made?

Authorities believe New York City gunman Tamura intended to target the NFL headquarters but ended up at the wrong location after taking the incorrect elevator. “From our preliminary investigation, he took the wrong elevator bank up to the NFL headquarters,” Mayor Eric Adams told CBS Mornings. “Instead, it took him to Rudin Management, and that is where he carried out additional shootings and took the lives of additional employees.”

Tamura travelled from his home in Las Vegas to Manhattan, passing through Colorado and New Jersey in his black BMW. Surveillance footage captured the chilling moment he entered the building, dressed in a sports coat and button-down shirt, calmly carrying an M4 rifle. On the skyscraper’s 33rd floor, he opened fire, killing four people, including an off-duty police officer, before taking his own life. President Donald Trump condemned the incident, calling the shooter a “crazed lunatic” who committed a “senseless act of violence” in his “beloved” native city.

NFL commissioner speaks to employees

NFL Commissioner Roger Goodell reassured staff in a memo on Tuesday that all employees are safe and accounted for following the shooting at the league’s Manhattan headquarters. “One of our employees was seriously injured in this attack. He is currently in the hospital and in stable condition,” Goodell wrote in the memo, which was obtained by ESPN. “NFL staff are at the hospital and we are supporting his family. We believe that all of our employees are otherwise safe and accounted for, and the building has nearly been cleared.” Goodell commended law enforcement for their swift response and paid tribute to the NYPD officer who lost his life in the shooting. Employees in New York were asked to work remotely or take the day off on Tuesday. Additional security measures will also be put in place, the memo noted. “Every one of you is a valued member of the NFL family. We will get through this together,” Goodell said.
