Medical examiners confirmed that Shane Tamura suffered from chronic traumatic encephalopathy when he attacked a Manhattan office building in July. The 27-year-old gunman traveled from Las Vegas before killing four people near the NFL headquarters. Tamura left a three-page letter blaming the league for concealing brain injury dangers from players.
The brain disease stems from repeated head trauma commonly seen in contact sports. Tamura entered the building at 6:30 p.m. and fired 47 rounds within minutes. He killed security guard Aland Etienne, Blackstone executive Wesley LePatner, police officer Didarul Islam, and Rudin Management worker Julia Hyman before taking his life.
The NFL expressed grief over the deaths while stating no justification exists for the violence.
