Former NFL Critic Suffered from CTE, Triggering Deadly Mass Shooting

A Manhattan office worker, 27-year-old Shane Tamura, who blamed the NFL for hiding the dangers of brain injuries, suffered from low-stage CTE, a degenerative brain disease commonly linked to repetitive head trauma. Tamura shot himself in the chest after a July 28 mass shooting that killed two others, leaving behind a haunting message for the NFL: "Study my brain." Tamura had twice been hospitalized for mental health crises and had expressed concern about the link between football and CTE. The NFL has conceded the link between football and CTE and has paid over $1.4 billion to retired players to settle concussion-related claims.
