345 Park Avenue Mass Shooting: Timeline, Motive & Victims (July 28, 2025)
On the evening of July 28, 2025, an active shooter stormed into the 44‑story office tower at 345 Park Avenue in Midtown Manhattan—home to the NFL headquarters and major firms—and left four people dead before turning the gun on himself.
📅 Timeline of Events
- **6:28 PM**: Surveillance video shows 27‑year‑old **Shane Devon Tamura** exiting a double‑parked black BMW on Park Avenue carrying an M4-style rifle near 51st and 52nd streets 1.
- He entered the lobby of the skyscraper and immediately shot NYPD Officer **Didarul Islam**, who was off-duty and serving detail inside 2.
- Several civilians, including a woman hiding behind a pillar and a building security guard, were also shot as Tamura moved through the lobby 3.
- Tamura took the wrong elevator—meant for NFL employees—and went to the Rudin Management office on the **33rd floor**, where he killed another person before committing suicide 4.
👤 Suspect Profile & Mental Health
Authorities identified the shooter as **Shane Devon Tamura**, 27, a former high school football player and former casino security employee in Las Vegas. He had no professional football history but carried a concealed carry permit in Nevada since 2022. Records also revealed two mental health crisis holds in 2022 and 2024 5.
📄 The Note & Allegations Against NFL
A handwritten suicide note discovered in Tamura’s possession blamed the NFL for his suffering, claiming he had **Chronic Traumatic Encephalopathy (CTE)**—a progressive brain disease tied to repetitive head trauma. He requested that his brain be studied post-mortem and referenced the documentary "League of Denial" and neurologists like Dr. Ann McKee and Dr. Christopher Nowinski. He cited former NFL player **Terry Long** as inspiration, who took his own life after a CTE diagnosis 6.
💥 Victims & Aftermath
Four people lost their lives in the attack:
- **Officer Didarul Islam** – a 36-year-old NYPD officer from Bangladesh, survived by a pregnant wife and two young sons 7.
- **Wesley LePatner** – a respected executive at Blackstone, remembered as warm and dedicated 8.
- **Aland Etienne** – building security guard shot at his desk 9.
- An unnamed fourth civilian was also killed; one NFL employee suffered serious injuries but is expected to recover 10.
New York Mayor **Eric Adams** ordered city flags to be flown at half-staff in honor of the victims, and **NFL Commissioner Roger Goodell** praised the heroism of first responders; many affected firms temporarily closed operations for security reviews 11.
🔎 Ongoing Investigation & Broader Implications
Authorities, including the FBI, are continuing to investigate Tamura’s motive, mental health background, and whether any ideological or personal grudges were involved. No link to organized terrorism has been identified as of now 12.
🧠 What Is CTE—and Why It Matters
**Chronic Traumatic Encephalopathy (CTE)** cannot be diagnosed in living individuals and is confirmed only via post-mortem brain analysis. It has been linked to cognitive decline, mood disorders, and suicidal behavior—particularly in former contact sport athletes. Experts warn that even repeated hits in youth or high school football players may lead to CTE symptoms later in life 13.
📌 Key Takeaways
- The mass shooting at 345 Park Avenue marks one of New York City's deadliest in recent years.
- Tamura’s note reveals his belief that he suffered from CTE and blamed the NFL—despite never playing professionally.
- The attack sparked renewed debate over gun laws, mental health policy, and brain injury research in the U.S.
