Phil Taitt reports from the scene of the shooting in Midtown.
MANHATTAN, New York (WABC) — The 27-year-old man who shot and killed four people at a Midtown office building on Monday carried a note in his pocket claiming he suffered from CTE, asked that his brain be studied and made references to the NFL, police sources told ABC News.
The suspect, Shane Tamura, who the police said has a documented mental health history, played high school football.
A former teammate of his spoke to our sister station KABC about Tamura.
“He was a great teammate. He was a great guy in general. He didn’t cause any problems actually at all in the locker room or on the field,” he said. “He was just a guy who really enjoyed the sport, not problematic at all so when I found out the news, I was really shocked, I really couldn’t believe it.”
Kemberly Richardson has more details on the gunman’s motive.
Sources described the three-page letter as rambling and contained references to the NFL. The references were found to be vague by the sources.
345 Park Avenue houses, among other companies, the NFL headquarters.
Tamura had two Mental Health Crisis Holds in his background in Nevada, one in 2022 and the other in 2024.
This typically allows someone to be detained for up to 72 hours if they are thought to be a danger to themselves or others.
According to one source, when there is this type of hold in Nevada, officers have to transport the person to the hospital. Once that happens, medical staff take over and decide how long to hold the person. They don’t update police so source isn’t sure how long Tamura was held either time.
A Las Vegas police source said Tamura also got his CCW (concealed carry) in 2022 and also has a previous arrest for trespassing in the state.
Tamura died of a self-inflicted gunshot wound in a 33rd floor office where he had barricaded himself.
