The 27-year-old shooter, identified as Shane Devon Tamura, drove cross-country from Las Vegas before opening fire at 345 Park Avenue with an M4 assault-style rifle, according to police officials cited by CNN. The attack occurred during rush hour at the skyscraper housing corporate offices for the National Football League and other major companies.
The shooting began at approximately 6:28 p.m. when Tamura entered the building's lobby and immediately opened fire on an NYPD officer and others present. Surveillance footage shows the gunman exiting a double-parked black BMW alone before entering the skyscraper, according to New York Police Department Commissioner Jessica Tisch.
"He then shoots a woman who took cover behind a pillar and proceeds through the lobby, spraying it with gunfire," Tisch stated during a news conference. The gunman continued to the elevator bank, where he shot a security guard taking cover behind his desk, before allowing a woman to exit an elevator unharmed and proceeding to the 33rd floor.
CNN described the Manhattan gunman, 27-year-old Shane Tamura of Las Vegas, as "possibly white."

On the 33rd floor, occupied by Rudin Management, Tamura fired multiple rounds while walking the floor, killing one person before shooting himself fatally in the chest, according to police accounts reported by CNN. Retired NYPD Captain John Monaghan told CNN that the gunman's calm approach to the building suggested "he knew he was going to die" and "was at peace with that."
A suicide note found in Tamura's pocket revealed his grievances against the NFL and his belief that he suffered from chronic traumatic encephalopathy (CTE), a brain disease linked to head trauma. The handwritten note, scribbled across three pages, stated "Terry Long football gave me CTE and it caused me to drink a gallon of antifreeze" and "You can't go against the NFL, they'll squash you," according to a source with knowledge of the investigation cited by CNN. Terry Long, a former Pittsburgh Steelers player who was diagnosed with CTE, died by suicide after drinking antifreeze in 2005. Tamura's note also requested that his brain be studied and included an apology to someone named Rick, CNN reported.

Multiple sources told CNN that Tamura had been a competitive football player in his youth. The gunman had "a documented mental health history," according to police statements, though his specific motives remain under investigation. A childhood friend of Tamura, who requested anonymity, told CNN he remembered the suspect as "a nice guy and a good athlete" and expressed shock at the development, saying he did not think it was something Tamura was capable of.
The attack timeline shows Tamura drove through Colorado on July 26, then through Nebraska and Iowa on July 27, before entering New York City around 4:24 p.m. on Monday, approximately two hours before the shooting began, according to police information.
Upon searching Tamura's vehicle, police discovered a loaded revolver, rifle case, ammunition, magazines, a backpack, and prescribed medication. No explosives were found. Tamura possessed a valid license to carry a weapon in Nevada, where obtaining such permits requires only proof of residency and absence of felony convictions or restraining orders, according to analysis provided to CNN.

Among those killed was NYPD Officer Didarul Islam, a 36-year-old immigrant from Bangladesh who was working security at the building. Islam, described by officials as a hero, leaves behind two young sons and a pregnant wife expecting their third child. "He loved this city and everyone we spoke with stated he was a person of faith and a person that believed in God and believed in living out the life of a godly person," New York City Mayor Eric Adams said of Islam during a Monday news conference, according to CNN.

One person who was shot survived and remains in critical but stable condition, while four additional victims received treatment for minor injuries sustained while fleeing the scene. An NFL employee was seriously injured but is stable, according to a staff memo from NFL Commissioner Roger Goodell, reported by CNN.
Eyewitnesses described hearing rapid gunfire and seeing people fleeing as the attack unfolded. "It felt like it was a quick two shots and then it was rapid fire," Nekeisha Lewis told the Associated Press, according to CNN's reporting. She described windows shattering and seeing a man run from the building, saying, "Help, help. I'm shot."
The 44-story building at 345 Park Avenue houses offices for the NFL, global investment firm Blackstone, tax and audit firm KPMG, and a Bank of America center. The NFL's corporate offices are located on the fifth floor of the building, which occupies an entire city block between 51st and 52nd Street.
The shooting represents the 254th mass shooting in the US this year, according to data from the Gun Violence Archive cited by CNN. The last time New York City experienced a mass shooting as deadly occurred in 2000, when two gunmen killed five people during a robbery at a Wendy's restaurant in Flushing, Queens.
