The man who killed four people in a rampage with a rifle through a Midtown Manhattan office building was carrying a note that appeared to blame the Football League for his degenerative brain disease, New York Mayor Eric Adams said on Tuesday.

Police have identified the shooter as Shane Tamura, a 27-year-old Las Vegas resident with a history of mental illness struggles, who ended the Monday evening massacre by shooting himself in the chest on the 33rd floor of a Park Avenue office tower.

The NFL has its headquarters in the skyscraper, but Tamura apparently entered the wrong elevator bank and ended up in the offices of Rudin Management, a real estate company, where he shot employees, the mayor said.

“The note alluded to that he felt he had CTE, a known brain injury for those who participate in contact sports," Adams told CBS News. “He appeared to have blamed the NFL for his injury."

Chronic traumatic encephalopathy is a serious brain disease with no known treatment that can be caused by repeated bangs to the head from contact sports. It has been linked to aggression and dementia, and the NFL has paid an estimated $1 billion to settle concussion-related lawsuits with thousands of retired players after the deaths of several high-profile players.

Tamura was never an NFL player, but online records show he played in high school. The note found in his wallet said his football career was cut short by his brain injury, Bloomberg News reported.

Blackstone also has its headquarters in the tower, and one of the private equity firm’s executives was among those Tamura killed, while others were injured and taken to hospital.
