Past security: A gunman walked into a skyscraper in Midtown Manhattan yesterday evening and began shooting, killing four people and injuring a fifth. Three of the people were killed in the building's lobby, including a New York City Police Department officer, 36-year-old Didarul Islam. The fourth person was killed on the 33rd floor. Among the dead are one Blackstone executive and one NFL employee, though names have not yet been released.
The shooter has been identified as 27-year-old Nevada man Shane Devon Tamura. Tamura killed himself soon after shooting his final victim. Law enforcement says he has a "documented mental health history" but gave no details as to what that entails. His firearm appears to have been legally obtained.
Tamura's suicide note alleged that he suffered from chronic traumatic encephalopathy, or CTE, a brain disease linked to head trauma, according to a source. "In the note, he asked that his brain be studied and wrote: 'You can't go against the NFL, they'll squash you,'" per CNN. "Multiple sources told CNN Tamura was a competitive football player in his youth. CTE is commonly associated with football players, and studies show that repetitive hits to the head can result in the disease. The NFL offices are on the fifth floor of the office tower that Tamura attacked."
