NYC gunman Shane Tamura’s brain will be studied after shooter blamed CTE for massacre
Manhattan Mass Shooter Shane Tamura’s Autopsy Reveals Self-Inflicted Gunshot Wound
Shane Tamura, the gunman responsible for the deadly attack in a Midtown office building, will have his brain examined as part of his autopsy after he blamed a football-related head injury for his actions, officials have confirmed.
The New York City Medical Examiner has determined that the 27-year-old gunman died by suicide following his rampage inside the office building, which houses the NFL’s headquarters, on Monday night. Tamura’s official cause of death was a self-inflicted gunshot wound to his torso, according to the medical examiner.

No official ruling has been made yet on whether Tamura was suffering from chronic traumatic encephalopathy (CTE), the brain disease he claimed to have had. The medical examiner stated that a neuropathology expert is conducting additional testing on the gunman’s brain for the complete autopsy record.
CTE is a degenerative brain disease caused by concussions and repeated blows to the head, and can only be diagnosed posthumously by examining the brain.
In addition to Tamura, the medical examiner has determined the cause of death for each of the shooter’s four victims:
- NYPD Officer Didarul Islam
- Blackstone executive Wesley LePatner
- Security guard Aland Etienne
- Rudin employee Julia Hyman
All four victims died from gunshot wounds to their torsos, according to the medical examiner’s office.
