NEW YORKâ A gunman who killed four people inside a Manhattan office tower blamed his mental health problems on the National Football League and intended to target its headquarters but took the wrong elevator, officials said Tuesday.
Shane Tamura, a Las Vegas casino security worker, was carrying a handwritten note in his wallet that claimed he had chronic traumatic encephalopathy, known at CTE, investigators said. He accused the league of hiding the dangers of brain injuries linked to contact sports.
Tamura, 27, sprayed the skyscraperâs lobby with bullets then shot another person in a 33rd-floor office on Monday before he killed himself, authorities said. Among the dead were a police officer, a security guard and two people who worked at companies in the building. An NFL employee was badly wounded but survived.
The attackerâs grievances with the NFL emerged as police worked to piece together his background and motivations, and as loved ones began to mourn the dead.
Itâs unclear whether Tamura showed symptoms of CTE, which can be diagnosed only by examining a brain after death.
Tamura, who played high school football in California a decade ago but never played in the NFL, had a history of mental illness, police said without giving details. In the three-page note found on his body, he accused the NFL of concealing the dangers to playersâ brains for profit. The degenerative brain disease has been linked to concussions and other repeated head trauma common in contact sports such as football.
Detectives planned to question a man who supplied gun parts for the AR-15-style rifle used in the attack, including the weaponâs lower receiver, Police Commissioner Jessica Tisch said in a video statement.
She and members of the force also paid tribute to Officer Didarul Islam, who was guarding the building on a paid security job when he was killed. His flag-draped remains arrived late Tuesday afternoon at the Bronx mosque preparing for his funeral.
A multifaith vigil
Mayor Eric Adams visited the scene and recalled working in the mailroom of the building as a young man.
âTo have to walk through and see the remnants of violence at that level, tore at me,â he told mourners at an evening multifaith vigil for those killed.
Muslim, Sikh, Buddhist, Hindu, Christian and other faith leaders delivered prayers at the gathering held at a park about a dozen blocks from where the shooting took place.
Both Adams and Gov. Kathy Hochul spoke of the need for stronger gun laws. Hochul said guns designed to kill people on battlefields shouldnât be in New York buildings.
âWe cannot respond to senseless gun laws through vigils,â Adams said.
NFL boss calls shooting âunspeakableâ
Tamuraâs note repeatedly said he was sorry and asked that his brain be studied for CTE. He mentioned a PBS Frontline documentary about the disease and referred to former NFL player Terry Long, who was diagnosed with CTE, and the manner in which Long killed himself in 2005.
The NFL long denied the link between football and CTE, but it acknowledged the connection in 2016 testimony before Congress and has paid more than $1.4 billion to retired players to settle concussion-related claims.
NFL Commissioner Roger Goodell, who works out of the offices, called the shooting âan unspeakable act of violence,â saying he was deeply grateful to the law enforcement officers who responded.
Goodell said in a memo to staff that the injured NFL employee was hospitalized in stable condition.
The shooting happened at a skyscraper on Park Avenue, one of the nationâs most recognized streets, just blocks from Grand Central Terminal and Rockefeller Center. It is less than a 15-minute walk from where UnitedHealthcare CEO Brian Thompson was shot and killed last December by a man who prosecutors say was angry over what he saw as corporate greed.
Mondayâs attack drew a response from the White House, with President Donald Trump posting that his âheart is with the families of the four people who were killedâ and that the officer âmade the ultimate sacrifice.â
