Tamura Case
When the Brain Fails Us: Understanding the Tamura Case
On July 28, 2025, 27‑year‑old Shane Tamura carried out a deadly shooting inside the NFL’s headquarters in Midtown Manhattan, killing four people—including an off-duty NYPD officer—and then himself. His three‑page suicide note claimed he suffered from chronic traumatic encephalopathy (CTE), requested his brain be studied after death, and blamed the NFL for his condition.
Although Tamura played football only at the high‑school level, he linked his mental health struggles to brain injury sustained in youth sports and alleged a causal role for CTE—even citing another affected player, Terry Long.
