A 27-year-old who killed four people and himself in a July shooting at an office tower in Manhattan had the degenerative brain condition chronic traumatic encephalopathy (CTE), according to the New York City medical examiner.
The office “found unambiguous diagnostic evidence” of a low-stage case of CTE in the brain tissue of the gunman, Shane Devon Tamura, 27.
Tamura, a former high school football player, claimed to be suffering from the condition, and the shooting targeted a building that’s home to offices of the NFL, whose athletes are prone to getting CTE.
