The suspect accused of killing four people in a Manhattan high-rise building on July 28, 2025, allegedly left a note behind that appeared to blame the NFL for a brain injury, according to New York City Mayor Eric Adams. The alleged attacker, 27-year-old Shane Tamura of Las Vegas, committed suicide by shooting himself after he allegedly opened fire at the 345 Park Avenue building that houses the NFL’s headquarters, along with other businesses. During an interview on CBS News, Adams was asked about a possible motive in the shooting. The mayor said that a note was allegedly found stating the shooter felt he had chronic traumatic encephalopathy, a brain injury more commonly known as CTE that some football players have been known to develop. “He appeared to have blamed the NFL for his injury,” Adams said. A media search found no one with the name Shane Tamura ever played in the NFL, including on teams’ practice squads. What caused this state of mind, and to kill because of it?61 views0 answers0 votes
