A mass shooting rocked Midtown Manhattan on July 28, 2025, when gunfire erupted inside 345 Park Avenue, a skyscraper that houses the global headquarters of Blackstone, the NFL, and KPMG. The NYPD confirmed the identity of the gunman as Shane Devon Tamura, a 27-year-old former security worker from Las Vegas. Tamura killed four people—including an NYPD officer—and injured several others before taking his own life.
Who Was Shane Tamura?
Shane Tamura was a Nevada resident with a background in private security. He legally owned multiple firearms and possessed a valid concealed carry license. According to authorities, Tamura had a known history of mental health issues, though no prior criminal record. Investigators are examining his online activity and personal communications to determine whether he had a specific target in the building or if the attack was more broadly motivated.
Timeline of the Shooting
The attack began shortly after 6:30 p.m. Tamura entered the building’s main lobby dressed in tactical gear, including body armor and an M4-style assault rifle equipped with a suppressor. He opened fire immediately, fatally shooting Didarul Islam, a 36-year-old off-duty NYPD officer working private security at the site.
Three more civilians were killed in the lobby before Tamura made his way to the 33rd floor. There, he shot one additional victim, reportedly an employee of the NFL, and then turned the weapon on himself.
First responders arrived within minutes. NYPD tactical teams secured the scene floor-by-floor while staff were evacuated or sheltered in place. Police later confirmed Tamura acted alone.
Victims of the Tragedy
Among the victims:
- Didarul Islam, an NYPD officer remembered for his bravery. Officials say his actions slowed Tamura’s movement and likely saved lives.
- Two other victims, whose names were not immediately released, were Blackstone and KPMG employees, according to internal memos.
- A fifth victim, a woman in her 30s, was gravely injured but is currently in stable condition at Bellevue Hospital.
The Building: 345 Park Avenue
The 44-story tower is among Manhattan’s most high-profile office spaces. It houses:
- Blackstone, one of the world’s largest investment firms.
- The NFL's headquarters, which span multiple floors.
- KPMG, one of the Big Four accounting firms.
The building is managed by Rudin Management, a major real estate firm. As of now, all companies inside the building have moved to remote operations pending further security reviews.
Motive and Mental Health Concerns
Tamura left behind a digital manifesto and a physical suicide note. In the materials, he allegedly blamed the NFL for his declining mental health, citing repeated head trauma from his time playing high school and semi-pro football. He believed he was suffering from chronic traumatic encephalopathy (CTE) and expressed a desire for his brain to be studied after death.
While Tamura had no employment or known contact with the companies targeted, investigators are probing possible links to individuals within the building and online forums he frequented.
Law Enforcement and Political Response
NYPD Commissioner Jessica Tisch praised the rapid response of emergency personnel and described the shooting as “a premeditated act of violence with signs of deep psychological distress.”
Mayor Eric Adams called for a citywide review of private building security, particularly in properties with high-profile tenants. Governor Kathy Hochul added that the state will work with federal agencies to analyze gun procurement and transportation across state lines.
The FBI confirmed that Tamura brought the weapon and gear from Nevada, bypassing security checkpoints by driving cross-country.
What Happens Next
Authorities continue to analyze security footage, social media posts, and Tamura’s online activity. There is currently no indication that anyone else was involved in planning the attack. The building’s tenants have committed to cooperating with law enforcement as they investigate gaps in access control and security protocols.
A Community in Mourning
New Yorkers gathered near the site to honor the victims. A vigil was held outside the building on the evening of July 29, with candles, flowers, and posters thanking first responders.
Officer Islam’s family issued a brief statement asking for privacy and requesting that the public remember him as a devoted father and public servant.
This tragedy has reignited debates around gun access, mental health care, and security in high-rise buildings. As the city heals, officials remain focused on ensuring that an event like this never happens again.
