A Blackstone executive killed during a horrifying mass shooting in Midtown Manhattan was one of four people fatally gunned down on July 28, 2025. The shooting unfolded at 345 Park Avenue—a towering office building that houses firms like Blackstone, KPMG, and Rudin Management. The suspect, identified as 27-year-old Shane Tamura, opened fire inside the lobby with a semi-automatic rifle before making his way to an upper floor, where he ended the massacre by turning the gun on himself.
According to investigators, Tamura arrived outside the building in a black BMW around 6:30 p.m. and immediately began shooting upon entering. The first victim was an on-duty NYPD officer assigned to the area. Within moments, three more individuals were killed, including the unnamed Blackstone executive and a security guard. Another victim was shot on the 33rd floor, believed to be an employee of a different firm.
Details of the Midtown Tragedy
Initial reports from witnesses describe chaos erupting in the building’s lobby as Tamura stormed in. Office workers scrambled for safety, barricading themselves inside conference rooms and restrooms while alerting others via emails and messaging apps.
Surveillance footage captured Tamura wielding a military-style rifle and carrying additional ammunition. He appeared calculated, firing into corners and behind furniture where people were trying to hide. After his rampage in the lobby, he took an elevator to a higher floor, where one more person was killed before Tamura died by suicide.

About the Shooter
Shane Tamura, a 27-year-old from Las Vegas, reportedly drove across several states before arriving in New York just days before the incident. Law enforcement confirmed he had a documented history of mental health issues and was armed with an M4 rifle and a revolver, along with extra magazines and prescription medications found in his vehicle.
Investigators believe Tamura may have intended to target a different office within the building. A written note found on his body mentioned confusion with elevator controls, indicating he may have reached the 33rd floor unintentionally.
Authorities Respond
Mayor Eric Adams called the incident “a gut-wrenching tragedy” and ordered city flags to be flown at half-staff in honor of the fallen officer. NYPD officials praised Officer Islam for attempting to shield others from the shooter’s bullets, referring to him as a hero who gave his life in the line of duty.
Emergency services responded within minutes, securing the building and treating survivors. Midtown Manhattan was locked down for hours, with nearby buildings and subway stations temporarily closed. Streets around Park Avenue were cordoned off until the area was deemed safe.
Corporate & Community Reaction
Blackstone, one of the world’s largest investment firms, issued a statement expressing sorrow and confirming the loss of one of its own. “We are devastated. Our hearts go out to the families and colleagues affected,” the statement read. The building remained closed to all non-essential personnel the following day.
The sudden and violent nature of the attack has reignited discussions about workplace security and mental health resources. As city leaders and corporate executives work to understand the shooter’s motive, many are asking how such a deadly act could occur in a high-security facility in the heart of New York City.
What’s Next?
As investigations continue, authorities are reviewing building security logs, surveillance footage, and the shooter’s digital history. A full forensic report is expected later this week. Meanwhile, grief counselors and crisis support teams have been dispatched to assist survivors and employees.
This tragic event has left a lasting impact on the Midtown business district. The death of a Blackstone executive, a loyal officer, and two innocent civilians has shaken the city. As New York mourns, the conversation about safety in high-profile buildings takes on new urgency.
