Its objective was to attack the headquarters of the NFL, the National Football League of the United States.

That is what almost all the indications of the crime that Shane Devon Tamura, 27, and resident of Las Vegas, perpetrated Monday afternoon in the Financial District of New York.

The attacker led a vehicle through the United States from Las Vegas to New York, separate cities more than 4,000 kilometers by road, according to the first investigations.

Armed with an assault rifle, he broke into the lobby of a skyscraper in Manhattan, where the NFL (National Football League) and other important companies are based, and began to shoot indiscriminately.

Then he took the elevator to the 33rd floor – who houses the Rudin Management office, owner of the building – and shot a woman before committing suicide of a shot.

In total he killed four people; The other three are a police officer who worked on security guard and two employees, one of them from the NFL.

The note that left

When reviewing the body of the aggressor, a three -page note was found that seems to give light on the reason for the attack, and whose content was revealed by authorities and media in the United States.

Tamura claimed that he suffered chronic traumatic encephalopathy (etc), a progressive neurodegenerative disease that is associated with brain shocks and other repetitive blows in the head suffered over time.

In the brief, the attacker asked to examine his brain in search of signs of etc.

The Mayor of New York, Eric Adams, told the media on Tuesday that the authorities “have reasons to think that (the attacker) was focused on the NFL.”

“It seems he blamed the NFL of his etc … and shot and removed his life. He shot in his chest. It seems he wanted to preserve his brain for research purposes,” Adams said.

This disease can only be definitively diagnosed after death, through a neuropathological examination of brain tissue.

Tamura blamed the chronic traumatic encephalopathy of the mental problems she suffered, reflected in a long medical history, and accused the NFL of hiding the dangers of this sport, police reported.

The aggressor had played American football in his adolescence, but did not reach the NFL, as reported by teammates to US media.

Shane Devon Tamura was the son of Terence Tamura, an American navy specialist who is currently active, according to his service sheet to which the BBC accessed.

A risk sport

Numerous medical studies in the last decade have established a strong association between the practice of American football and etc.

American football is a high -impact sport where players suffer frequent blows in the head, both in the form of clinically detectable brain shocks and subcontibly impacts or minor blows without immediate symptoms.

This means that those who practice this sport – especially professionally, but also at a youth level – face a significantly higher risk of degenerative brain damage compared to the general population, according to several studies.

Monday's incident paralyzed several parts of the Manhattan central strip and public transport.

A BBC journalist in the place reported having seen dozens of police vehicles and at least a person with a bloodied chest being transported on a stretcher.

The police were evicted by the floor building by floor, a work that lasted hours, while face -to -face witnesses described the horror that was lived during and after the events.
