On July 28, 2025, a tragic shooting at 345 Park Avenue in Midtown Manhattan left four people dead, including an NYPD officer, and one seriously injured. The gunman, identified as 27-year-old Shane Devon Tamura, took his own life on the 33rd floor of the building, which houses the headquarters of the National Football League (NFL) among other major tenants. A note found on Tamura’s body revealed deep-seated grievances against the NFL, specifically linking his actions to chronic traumatic encephalopathy (CTE), a degenerative brain disease associated with repeated head injuries. This devastating event has reignited debates about the NFL’s handling of CTE, mental health, and workplace safety in high-profile corporate settings.

The Shooting at 345 Park Avenue

The incident unfolded just before 6:30 p.m. when Tamura, a Las Vegas resident, exited a black BMW double-parked near 345 Park Avenue. Armed with an M4 rifle and wearing body armor, he entered the building’s lobby and immediately opened fire. According to NYPD Commissioner Jessica Tisch, Tamura fatally shot Officer Didarul Islam, a 36-year-old father of two with a third child on the way, who was working a paid security detail. He then shot a woman hiding behind a pillar and a security guard at a desk, before spraying the lobby with gunfire. Tamura allowed one woman to exit an elevator unharmed before taking it to the 33rd floor, where he killed another person at the offices of Rudin Management. He then died by a self-inflicted gunshot wound to the chest.

Among the victims was Wesley LePatner, a senior executive at Blackstone, described as a “beloved member” of the firm. An NFL employee was also seriously injured but is stable and receiving support from the league. The other victims’ identities have not been released pending family notification.

Shane Tamura’s Background and Motive

Shane Tamura, originally from Hawaii and later a resident of Las Vegas, was a former high school football standout. He played as a running back and defensive back at Golden Valley High School in Santa Clarita and Granada Hills Charter High School in Los Angeles, earning accolades for his performance, including 1,346 all-purpose yards and 11 touchdowns in the 2014–15 season. Despite his early promise, Tamura never advanced to college or professional football, a factor some speculate contributed to his resentment toward the NFL.

A multi-page suicide note found in Tamura’s pocket provided critical insight into his motives. In it, he blamed football for causing CTE, which he believed led to his mental health struggles. The note referenced Terry Long, a former Pittsburgh Steelers player who died by suicide in 2005 after suffering from CTE, stating, “Terry Long football gave me CTE and it caused me to drink a gallon of antifreeze. You can’t go against the NFL, they’ll squash you.” Tamura also requested that his brain be studied posthumously to confirm the presence of CTE, a condition only definitively diagnosed through autopsy.

Tamura had a documented history of mental health issues, as confirmed by Las Vegas authorities, and was prescribed medication found in his vehicle alongside a rifle case, a loaded revolver, and ammunition. He held a concealed carry permit issued in 2022 and an expired private investigator license, with a minor trespassing charge in 2023 as his only known criminal record.

Investigators are probing whether Tamura intended to target the NFL’s offices, located on the fifth through eighth floors, but ended up on the 33rd floor due to confusion with the building’s elevator banks. New York Mayor Eric Adams suggested Tamura “appeared to have gone to the wrong floor,” indicating the NFL may have been his primary target.

CTE and the NFL: A Growing Controversy

Chronic traumatic encephalopathy (CTE) is a progressive brain disease linked to repeated head trauma, commonly associated with contact sports like football. Symptoms include cognitive impairment, mood disorders, and behavioral changes, often manifesting years after injuries occur. A 2017 Boston University study found CTE in 110 of 111 brains of deceased former NFL players, highlighting the sport’s significant risks. Tamura’s note and actions have thrust the NFL’s handling of CTE back into the spotlight, raising questions about player safety and the league’s responsibility to former athletes, even those who never played professionally.

Tamura’s case underscores the broader impact of CTE concerns, particularly for young athletes whose dreams of professional sports may end abruptly, leaving them vulnerable to physical and mental health challenges. Social media speculation has linked Tamura’s failed football aspirations to his attack, though the NYPD has not officially confirmed this as the sole motive.

Aftermath and Broader Implications

The shooting has sent shockwaves through New York City, prompting vigils for the victims and a review of security protocols at high-rise commercial buildings. Mayor Adams ordered all city flags lowered to half-staff in honor of Officer Didarul Islam, described as a hero who “put himself in harm’s way” to protect others. The NFL, Blackstone, and other tenants like KPMG have expressed condolences, with NFL Commissioner Roger Goodell ensuring support for the injured employee and increased security at the league’s offices.

This tragedy has amplified calls for addressing mental health, gun violence, and sports-related injuries. Public health experts warn that Tamura’s case could fuel further debate about the long-term risks of contact sports and the NFL’s role in supporting affected athletes. Authorities are also investigating how Tamura legally acquired his high-powered firearm, adding to ongoing discussions about gun control in the U.S.

Conclusion

The 345 Park Avenue shooting is a stark reminder of the complex interplay between mental health, sports-related trauma, and gun violence. Shane Tamura’s attack, driven by his belief that football-related CTE contributed to his struggles, has cast a spotlight on the NFL’s responsibility to address the long-term effects of head injuries. As New York mourns the loss of four lives, including a dedicated NYPD officer and a respected Blackstone executive, the incident serves as a call to action for improved mental health resources, stricter workplace security, and greater awareness of the risks associated with contact sports.
