NEW YORK CITY — In a horrifying act of violence, four people were shot and killed and one critically injured when 27-year-old Shane Tamura opened fire inside a Midtown Manhattan office building at 345 Park Avenue, home to the NFL Headquarters, on Monday. According to law enforcement sources, Tamura left behind a disturbing note claiming he suffered from CTE (Chronic Traumatic Encephalopathy) and blamed the NFL for allegedly hiding the risks of brain trauma in football to protect profits.
The mass shooting, which unfolded on the 33rd floor at Rudin Management after Tamura mistakenly exited the wrong elevator, ended with the suspect dying by suicide. His note reportedly included statements such as, “Study my brain please. I’m sorry.”
Suspect’s Background Raises Red Flags
Authorities revealed that Tamura, originally from Nevada, had a history of mental health crises, including two Mental Health Crisis Holds — one in 2022 and another earlier this year. Despite his troubled past, he legally obtained a concealed carry permit (CCW) in 2022. Police also reported a prior trespassing arrest and traced his BMW’s interstate journey, confirming he arrived in New York just two hours before carrying out the deadly attack.
At the scene, investigators recovered an AR-15-style M4 assault rifle, which was covered in blood. Law enforcement officials noted that Tamura had no known connection to the NFL, though he had played high school football in Los Angeles.
Victims and Aftermath
Among the deceased were a Blackstone executive, described as a devoted mother and wife, and a New York Police Department officer, a father of two with a third child on the way. The fifth victim, reported to be an NFL employee, underwent emergency surgery and is now in stable condition.
NFL Commissioner Roger Goodell confirmed the injury and announced increased security presence at 345 Park Avenue, directing employees to work remotely or take time off.
Political Response: Calls for National Assault Weapons Ban
New York Governor Kathy Hochul issued a strong statement condemning the attack and renewing her demand for a nationwide ban on assault weapons. “The killer used an AR-15-style weapon of war — the same kind used in countless mass shootings across America,” she said. “New York has some of the toughest gun laws in the country, but when firearms can easily cross state lines, our communities remain at risk.”
She ordered flags on all state buildings to fly at half-staff to honor the victims, declaring, “An attack on one of us is an attack on all of us.”
National Reaction
Former President Donald Trump responded via social media, expressing heartbreak over the tragedy. “I trust our law enforcement to get to the bottom of why this crazed lunatic committed such a senseless act,” he wrote. “My heart is with the families of the victims, especially the brave NYPD officer who gave his life.”
What is CTE?
Chronic Traumatic Encephalopathy (CTE) is a degenerative brain disease linked to repeated head trauma, often seen in football players, veterans, hockey players, and boxers. Symptoms include memory loss, confusion, mood swings, and cognitive decline. CTE can only be definitively diagnosed after death.
Though Tamura claimed in his note to suffer from CTE, investigators found no evidence of past brain injuries or a professional football career.
