Under Investigation, current information points to grievances with the NFL and CTE
On July 28, 2025, a mass shooting occurred at 345 Park Avenue in Midtown Manhattan, New York City, United States. The incident began at 6:28 p.m. EDT (UTC–4).[1] A gunman identified as 27-year-old Shane Tamura, wearing body armor,[2] fired a PSA PA-15 inside the building killing four people, including an New York City police officer who was off-duty and working as security.[3] Tamura committed suicide after barricading himself.[4] The mass shooting is the deadliest in New York City since the 2000 Wendy's massacre in Queens.[5] The perpetrator's motive is being investigated by police.

The gunman left his home in Las Vegas on July 26 driving to New York City, with several stops en route. The first was in Colorado on July 26, and another between Nebraska and Iowa on July 27; he also stopped in Columbia, New Jersey, on July 28 shortly before arriving in New York City.[6]
After parking his car nearby, Tamura walked inside the Park Avenue building, where he fatally shot police officer Didarul Islam and a woman who had taken cover behind a pillar. He then sprayed the lobby with gunfire, hitting a man before shooting a security guard at the elevators. According to Police Commissioner Jessica Tisch, he allowed a woman who was inside the elevator to walk away unharmed[7] before exiting on the 33rd floor where Rudin Management's office is located. Tamura shot Julia Hyman and then barricaded himself on the 33rd floor, where he fatally shot himself in the chest.[8] The emergency response to the mass shooting included police, firefighters, and the Federal Bureau of Investigation.[9]
Investigators believe that Tamura intended to target the National Football League (NFL), which has offices on multiple floors in the building, but went to the wrong bank of elevators, taking one to the 33rd floor.[10] Officials said the suspect acted alone.[11]
Victims
The perpetrator killed four people and critically injured another person.[12]Didarul Islam, a 36-year-old off-duty police officer working as a security guard in NYPD uniform, was shot in the back and died while undergoing surgery. He was saluted by citizens and police in the street as he was transferred to an ambulance. Another victim was Wesley LePatner, the CEO of Blackstone Real Estate Investment Trust.[5] Julia Hyman, a 27-year-old 2020 Cornell University graduate working for Rudin Management,[13] was identified as one of the four people killed[14] as was Aland Etienne, a 46-year-old security guard.[15] A member of the NFL's staff who worked in the finance department was seriously injured in the attack when he was struck in the back by a bullet.[16] Four people suffered minor injuries while fleeing the scene.[17][18]
Tamura was a surveillance department employee (he worked in security) at Horseshoe Las Vegas, a casino in Paradise, Nevada according to a statement released by Caesars Entertainment.[25] According to CNN, he had a concealed carry license for a handgun and had an expired private investigator license. At the time of the shooting, he had a loaded revolver, magazines, ammunition, a backpack, and prescribed medication in his vehicle.[17][26] He did not have a significant criminal background.[27][28] According to officials in Las Vegas, Tamura had a documented mental health history, with two psychiatric holds in Nevada,[29] one in 2022 and another in 2024.[30]
Additionally according to the Las Vegas Review-Journal, Tamura was arrested in 2023 for suspicion of trespassing at the Red Rock Resort in Summerlin, Nevada. Law enforcement said that he was "agitated" and would not leave the premises.[31] He had a suicide note in his back pocket alleging that he suffered from chronic traumatic encephalopathy (CTE), a neurodegenerative disease which can result from involvement in contact sports. The note said, "Terry Long football gave me CTE and it caused me to drink a gallon of antifreeze," "Study my brain please I'm sorry, tell Rick I'm sorry for everything" and "You can't go against the NFL, they'll squash you." Long played in the NFL and was diagnosed with CTE. He died by suicide in 2005 after drinking antifreeze.[32] The identity of "Rick" is believed to be Tamura's supervisor at the Horseshoe casino where Tamura was last employed,[33] who had sold Tamura the BMW he drove to New York, as well as the lower receiver of the AR-15 he used in the shooting for $1,400.[34] A second, publicly undisclosed note also mentions CTE.[35]
Officers from the Las Vegas Metropolitan Police Department recovered his concealed carry license, which he obtained in 2022.[12] Reports indicated that Tamura had a concealed carry permit and no known criminal history with an exception of minor charges, including a trespassing charge in 2023 which was dropped a month later according to Clark County court records. His neighbors said they did not recognize Tamura but they recognized his car, which they said was driven in and out of their gated community of Desert Shores.[36] Records released by NBC News show that he had a work card issued by the Nevada Private Investigators Licensing Board from 2019 to 2024, but the work card did not authorize him to carry a firearm.[37]
Aftermath
A multi‑faith prayer vigil was held at Bryant Park in Manhattan the evening after the shooting. Mayor Eric Adams, Governor Kathy Hochul, Attorney General Letitia (Tish) James, Police Comissioner Jessica Tisch and religious leaders attended alongside hundreds of mourners. Flowers and candles were placed near the building and flags were flown citywide at half-mast in honor of the victims.[38]
Fundraisers for officer Didarul Islam and his family raised over $200,000.[39] Officer Islam was posthumously promoted to Detective First Grade at his funeral by Police Commissioner Jessica Tisch.[40]
Reactions
In a press conference, the mayor of New York, Eric Adams, said the shooting was a "violent, despicable" act. He called Didarul Islam a hero who put his life on the line. Adams said there needs to be more investigation.[41]
US President Donald Trump posted on Truth Social that he had been briefed on the situation. He said the shooting was a "senseless act of violence" and extended condolences to the victims' families.[42]
In a statement, New York Governor Kathy Hochul advocated for increased gun control "The time to act is now. The American people... deserve action. Congress must summon the courage to stand up to the gun lobby and finally pass a national assault weapons ban before more innocent lives are stolen."[43]
Investigation
After the shooting, NYPD officers searched Tamura's vehicle[44] and found a loaded Colt Python.357 Magnum revolver, ammunition, medication, and two cellphones.[45] Investigators reported that ammunition was purchased in June 2025 from a Las Vegas gun show after a visitor received a tip saying that Tamura had purchased large amounts of ammunition and an aftermarket trigger.[46]
