NYC Shooter Targeted NFL Offices, Left Suicide Note About CTE
Summary from the AllSides News Team
Authorities identified 27-year-old Shane Devon Tamura as the gunman in the Monday Manhattan shooting that killed five, including a New York City police officer.
The Details: The shooting took place inside an office tower that houses the offices for major companies such as the NFL and Blackstone. Authorities believe Tamura, who drove from Las Vegas and died via a self-inflicted gunshot wound, acted alone. A suicide note left suggests he suffered from Chronic traumatic encephalopathy (CTE) that he believed was the result of playing football and wanted his brain to be studied. The victims included a 36-year-old police officer, a Blackstone executive, and two other people. A fifth person was critically wounded by the Palmetto State Armory M4 assault rifle used by the gunman.
For Context: Tamura was a 27-year-old licensed private investigator from Las Vegas. He had a documented mental health history and had traveled cross-country before arriving in Manhattan. New York Mayor Eric Adams said Tamura was targeting the NFL headquarters, and it has been reported that Tamura played competitive football in his youth in Canada.
Key Quote: Tamura's note read, "[Football] gave me CTE and it caused me to drink a gallon of antifreeze. You can't go against the NFL, they'll squash you." NFL Commissioner Roger Goodell told NFL employees that an employee was injured and described the shooting as "an unspeakable act of violence."
How the Media Covered It: The story has been atop the front pages of many mainstream outlets since the shooting happened on Monday night. Several outlets have offered live coverage as new details have emerged. Angles emphasized in headlines have included the NFL and Blackstone being housed in the building, Tamura's stated desire for his brain to be studied, and New York Police Commissioner Jessica Tisch's claim that Tamura had a history of mental illness. A TV broadcast from CNN (Lean Left bias) initially referred to the gunman as "possibly white."
