At least four people were killed and another critically injured after a lone gunman stormed an office tower in Midtown Manhattan and opened fire, before turning the gun on himself, officials say.
Police said that Shane Tamura, 27, burst into the 44-story building at 345 Park Avenue – home to offices for the NFL and investment giant Blackstone – shortly before 6:30 p.m. on Monday, carrying an AR-15-style rifle. The suspect “immediately” opened fire, “spraying” the lobby with gunfire, Police Commissioner Jessica Tisch said at a news conference.
Tamura, a former high school football star from Southern California, left Las Vegas on Saturday, Tisch said. He died in Rudin Management’s 33rd-floor offices from a self-inflicted gunshot wound to the chest, she added.
New York City police officer Didarul Islam was among those killed in the crossfire. A Blackstone executive was also shot dead in the tower’s lobby, sources told the Wall Street Journal. The NFL said one of its employees was critically injured.
Investigators allegedly found a note on Tamura claiming that he suffered from chronic traumatic encephalopathy (CTE), a disease linked to head trauma, and asked that his brain be studied, a source told CNN.
Note reportedly found on gunman details anger at NFL and claims of CTE
In Shane Tamura’s pocket, investigators say they allegedly found a note claiming that he suffered from chronic traumatic encephalopathy (CTE), a disease linked to head trauma, and asked that his brain be studied, a source told CNN.
In the note, he allegedly expressed grievances against the NFL – which has its headquarters in the building he attacked – and requested that his brain be studied.
“Terry Long football gave me CTE and it caused me to drink a gallon of antifreeze,” it read, according to CNN. “You can’t go against the NFL, they’ll squash you.”
Former Pittsburgh Steelers lineman Terry Long was diagnosed with CTE. The former football player died by suicide after drinking antifreeze in 2005.
“Study my brain please I’m sorry Tell Rick I’m sorry for everything,” the note reportedly said.

Who is Didarul Islam? The NYPD officer killed in Midtown Manhattan shooting
New York City Police Department officer Didarul Islam was among four people gunned down in Monday evening’s shooting at the 345 Park Avenue office tower, officials say.
The 36-year-old Bangladeshi national had been off-duty, but working a private security job in the building when he was shot dead by suspect Shane Tamura, NYPD Commissioner Jessica Tisch said at a Monday press conference.
“He put himself in harm’s way, he made the ultimate sacrifice – shot in cold blood, wearing a uniform that stood for the promise that he made to this city,” she said.
“He died as he lived, a hero.”
Didarul had served in the NYPD’s 47th precinct in the Bronx for three and a half years, New York City Mayor Eric Adams told reporters.
Adams met with Islam’s family earlier Monday night and told them that “he was a hero and we admire him for putting his life on the line.”
Islam leaves behind his pregnant wife and two young sons.
