Gunman who blamed NFL for hiding brain injury dangers had CTE, medical examiner confirms

"Shane Tamura, 27, had unambiguous diagnostic evidence of low-stage chronic traumatic encephalopathy, commonly known as CTE, according to the New York City medical examiner. Tamura, a Las Vegas casino worker, shot himself in the chest after spraying bullets into the Manhattan office building on July 28, killing four people, including a police officer, a security guard and two people who worked at companies in the building. He had traveled across the country intending to target the NFL office, officials said, but took the wrong elevator."

"In a three-page note found in his wallet, Tamura said he had chronic traumatic encephalopathy diagnosable only after death and implored those who found him: Study my brain. Among his grievances against the NFL was a claim that the league put its profits ahead of player safety by concealing the harm CTE, and football, can cause. There is no justification for the horrific and senseless acts that took place, an NFL spokesperson said in response to the findings."

Shane Tamura, a 27-year-old former California high school football player, had unambiguous diagnostic evidence of low-stage chronic traumatic encephalopathy, according to the New York City medical examiner. Tamura traveled across the country aiming for the NFL office but took the wrong elevator and sprayed bullets inside a Manhattan office tower on July 28, killing four people and wounding an NFL employee. Tamura shot himself in the chest and left a three-page note saying CTE is diagnosable only after death and urging others to study his brain. He accused the NFL of putting profits ahead of player safety. The medical examiner noted that CTE affects regions of the brain involved in regulating behavior and emotions and that the science around the condition continues to evolve.
