A tragic mass shooting at 345 Park Ave. in Midtown Manhattan left four people dead and one critically injured. The suspect, identified as 27-year-old Shane Tamura, reportedly carried a note claiming he suffered from chronic traumatic encephalopathy (CTE) and referencing the NFL, whose headquarters are located in the same building.
What Happened in the Manhattan Shooting?
The shooting occurred at 345 Park Ave., a prominent office building housing the NFL’s headquarters and other businesses, including Rudin Management. According to police sources, Tamura entered the building, took an elevator to the 33rd floor, and carried out the attack at Rudin Management’s offices, not the NFL’s. He fatally shot four individuals, including NYPD officer Didarul Islam, and wounded a fifth person who is now in stable condition after surgery. Tamura then died by suicide.
New York City Mayor Eric Adams noted that Tamura appeared to blame the NFL for his condition, as mentioned in a note found in his pocket. The note also requested that his brain be studied for CTE, a degenerative brain disease linked to repeated head trauma.

What Is CTE and Its Connection to the NFL?
Chronic traumatic encephalopathy (CTE) is a progressive brain disease associated with repeated head trauma, commonly seen in athletes like football players, hockey players, and boxers, as well as military veterans. Symptoms include memory loss, mood swings, confusion, and cognitive difficulties, often appearing years after the initial trauma. CTE can only be definitively diagnosed post-mortem through an autopsy that examines the brain for tau protein changes.
The NFL has faced significant scrutiny over CTE due to the high incidence of head injuries in football. High-profile cases of former players diagnosed with CTE have raised awareness about the long-term risks of concussions and repetitive hits. Tamura’s note suggesting a connection to the NFL highlights ongoing concerns about the league’s responsibility in addressing player safety and brain health.
