Gunman In Midtown Mass Shooting Had CTE, Medical Examiner Says

NEW YORK CITY — The gunman in a Midtown mass shooting that killed four people in July had chronic traumatic encephalopathy (CTE) which was mentioned in his suicide note, the city's medical examiner announced Friday.

Shane Tamura, 27, had evidence of low-stage CTE, a brain disease that is linked to repeated head trauma.

The 27-year-old blamed the NFL for his condition and cited his mental health struggles in his suicide note, officials said. Tamura fatally shot himself inside 345 Park Ave. on July 28.

Tamura walked into the building carrying an AR-style weapon and made his way to the 33rd floor, where he opened fire.

NYPD Officer Didarul Islam, Wesley LePatner, a Blackstone executive, security officer Aland Etienne and Julia Hyman, a Rudin Management employee, were killed in the shooting.

Tamura wanted to shoot up the NFL’s offices on levels five through eight, but “mistakenly went up the wrong elevator banks” and ended up on a higher floor, officials said.

The shooter in his three-page-long note pleaded for his brain to be studied following his death.
