On Monday evening (July 28), Shane Tamura, 27, opened fire at around 6:30PM in the lobby of 345 Park Avenue, a luxury skyscraper that houses the NFL’s headquarters.
The shooter then proceeded to the 33rd floor, where he killed another person and then fatally shot himself in the chest.
A multi-page note was discovered after Tamura’s death, and authorities revealed that it contained long-harbored grievances against the National Football League (NFL) and included explicit references to CTE, a brain disease linked to repeated head trauma.
