During a Manhattan Mass Shooting, A former high school football player opened fire in a Manhattan office building, killing four, wounding one, and blaming the NFL for brain trauma in a suicide note
Introduction
In the Manhattan mass shooting incident that occurred on Monday evening, July 28, 2025, at an office building in Manhattan, three civilians and one off-duty police officer were killed with an assault rifle, and another person was critically injured and hospitalized, city authorities confirmed.
At an emergency press conference, Mayor Eric Adams and NYPD Commissioner Jessica Tisch stated that the shooter was identified as Shane Devon Tamura (27) from Las Vegas, who allegedly took his own life after entering the skyscraper at 345 Park Avenue and opening fire with an automatic rifle.

The building at 345 Park Avenue houses offices of major financial firms, including Blackstone and KPMG, as well as the NFL headquarters, which appears to have been Tamura’s intended target.
The Manhattan Mass Shooting
Tamura traveled from Las Vegas with the apparent intent to attack those at the building’s NFL offices. Security footage shows him exiting a black BMW with an M4 assault rifle just before 6:30 p.m. and entering the 44‑story tower at 345 Park Avenue, immediately opening fire on an NYPD officer in the lobby.
Police later discovered in his vehicle a loaded revolver, ammunition, a backpack, and medication prescribed to Tamura. CBS News
The first victim of the Manhattan mass shooting was Officer Didarul Islam (36), originally from Bangladesh, working as a security guard. After he was shot and killed, Tamura fired throughout the lobby, killing a woman hiding behind a pillar and two other civilians. Another man was critically injured and rushed to the hospital.

Tamura then proceeded to the elevators, shot a security guard, and wounded another individual in the lobby. Though he aimed to reach the NFL floors (5–8), he reportedly took the wrong elevator and ended up on the 33rd floor, where Rudin Management offices are located. There, he shot and killed another person before turning the gun on himself.

Civilians
Three civilians were also killed: a man, a woman, and a security guard. One of them was confirmed as a Blackstone executive described as “brilliant, warm, and deeply respected.”
A fifth person was critically injured in the lobby and remains hospitalized in stable condition after surgery. CBS News
Motive and Background of the Shooter
Tamura was a former high‑school football player and claimed to suffer from chronic traumatic encephalopathy (CTE), blaming the NFL for hiding health risks to players.
A three-page note found on him contained accusations and pleas: “Study my brain, please. I’m sorry,” and “Tell Rick I’m sorry for everything”, referring to someone named Rick.
The note also referenced former player Terry Long, who died by suicide from antifreeze poisoning and was diagnosed posthumously with CTE. ABC News
Law enforcement confirmed he had mental health holds in Nevada in 2022 and 2024, but he was not under FBI surveillance. He did legally hold a concealed-carry permit in Nevada, which allowed him to possess the weapons used in the attack.
Police and city officials have ruled out terrorism in this case of the Manhattan Mass Shooting, stating Tamura acted alone with no known organizational affiliations. CBS News
Conclusion & Broader Context
According to Gun Violence Archive, the Manhattan Mass Shooting was the 254th mass shooting in the U.S. in 2025—defined as incidents with at least four people killed or wounded. Wikipedia
The attack raises troubling questions: Were security protocols at the building insufficient? Should mental health systems or law enforcement have flagged Tamura earlier? What role do the NFL and broader sports institutions bear? And where does individual accountability begin?
While definitive answers may never emerge, one thing is clear: there were multiple systemic failures, unnecessary lives were lost, and families were destroyed, including the perpetrator's family, which was completely devastated.
254 mass shootings this year!!!!!
This country is going to hell
