What we know about the deadly Manhattan office shooting

preCharge News BUSINESS — Four people were killed in a shooting Monday evening inside a New York City office building. The gunman, who used a high-powered rifle to open fire in the Midtown Manhattan skyscraper, later died of a self-inflicted gunshot wound, police said.

A New York City police officer was among those killed in the shooting, in addition to three other people. Officials also said a man was hospitalized in critical condition.

Police have identified the shooting suspect as Shane D. Tamura, 27, of Las Vegas. New York City Mayor Eric Adams said investigators recovered a note in which Tamura appeared to blame his own traumatic head injury on the National Football League, which has offices in the building where the rampage took place.

The tower at 345 Park Ave. contains offices for several other major corporations, including the accounting firm KPMG and the investment company Blackstone.

President Trump said in a social media post that he had been briefed on the shooting, which he called “tragic” and “a senseless act of violence.”

Timeline of the Incident

What Happened?

Just before 6:30 p.m. on Monday, surveillance video showed the suspect, alone, exiting a black BMW that was double-parked on Manhattan’s Park Avenue between 51st and 52nd streets, New York City Police Commissioner Jessica Tisch said. In the video, the gunman is seen carrying an M4 rifle.

The suspect then entered the 44-story high-rise at 345 Park Ave., turned right and opened fire on an NYPD officer who was in uniform working a private security job as part of an NYPD program.

Tisch said multiple 911 calls came in shortly afterward to report an active shooter inside the building.

Shooting in the Lobby and Upper Floors

The gunman continued to open fire as he moved through the lobby, striking a woman who had tried to hide behind a pillar, officials said. Proceeding toward the lobby’s elevator bank, he shot a security guard who had sought shelter behind a desk, in addition to another man who told police he had also been shot in the lobby, according to the NYPD commissioner.

The suspect allowed a woman who stepped out of an elevator he was waiting for to pass by unharmed, Tisch said. Then, he rode the elevator to the 33rd floor, where the offices of the building’s owner, Rudin Management, are located. The commissioner said he “began walking the floor, firing rounds as he traveled,” and struck one of the victims who eventually died.

At that point, the gunman walked down the hallway and shot himself in the chest, Tisch said.

The Victims

Fallen NYPD Officer and Private Citizens

The police officer killed in the lobby has been identified as 36-year-old Didarul Islam, a four-year veteran of the NYPD based out of the 47th Precinct in the Bronx. Islam was working on a paid detail Monday as part of a program run by the police department that allows officers to provide security to private companies.

The Suspect: Shane D. Tamura

Background, Motive, and Mental Health

Police have shared preliminary details about Tamura, a 27-year-old former high school football player from Santa Clarita, California.

Investigators found a note in Tamura’s wallet referencing CTE, saying, “Study my brain please. I’m sorry.” He accused the NFL of concealing the dangers of traumatic brain injuries.

Tamura had a known mental health history and worked security at the Horseshoe Casino in Las Vegas. He failed to show up for work on Sunday.

Cross-Country Journey to New York

Tisch said Tamura drove from Las Vegas, crossing Colorado, Nebraska, Iowa, and New Jersey before arriving in New York. Surveillance confirmed his BMW passing through Columbia, New Jersey, at 4:24 p.m. Monday.

Officers found multiple weapons, ammunition, medication, and a rifle case in the vehicle. Some rifle parts were purchased by an associate, who is now being interviewed by NYPD in Las Vegas.

The handgun found in his vehicle was legally purchased with a concealed carry permit in Nevada.

Fallout and Political Response

Officials Condemn the Attack

Mayor Eric Adams called the attack “violent” and “despicable.” New York Gov. Kathy Hochul urged federal action, emphasizing the AR-15–style weapon used and calling for national assault weapon bans.
