New York City Mayor Eric Adams revealed that the gunman who killed four people and then committed suicide in a Manhattan skyscraper may have targeted the National Football League (NFL) offices because he blamed the league for brain injuries he claimed to suffer.
Authorities have identified the attacker as 27-year-old Shane Tamura. Police discovered a note that connected Tamura’s motive to chronic traumatic encephalopathy (CTE), a degenerative brain disease often diagnosed in athletes who participate in contact sports. This note provided the first insight into the shootings that paralysed central Manhattan late on Monday.

Mayor Adams informed CBS News that the suicide note suggested Tamura believed he had chronic traumatic encephalopathy (CTE) and held the NFL accountable for his injury. However, Adams clarified that Tamura never played in the NFL; he was instead known as a star high school football player in California.
