A tragic shooting in Midtown Manhattan on July 28 left five people dead, including an off-duty NYPD officer, after a gunman opened fire inside a high-rise office building that houses the NFL’s corporate offices.
The gunman, identified as 27-year-old Shane Devon Tamura of Las Vegas, entered 345 Park Avenue around 6:30 p.m., armed with an M4-style rifle and dressed in tactical gear. He immediately began firing in the lobby, fatally striking NYPD Officer Didarul Islam, who was working security, along with two civilians. He then rode the elevator to the 33rd floor and killed another person before turning the gun on himself.
Tamura reportedly drove cross-country to New York and had no known ties to the city or the building. A three-page note found on him referenced CTE (chronic traumatic encephalopathy) and grievances with the NFL, leading investigators to explore a possible motive linked to his mental health. He had a history of psychiatric holds in Nevada but no serious criminal record.
The shooting also left at least one other person critically injured. The NYPD and FBI continue to investigate how Tamura obtained and transported the firearms and whether his mental health played a direct role in the attack.
Suspect: Shane Devon Tamura
Age & residence: 27‑year‑old male, most recently living in Las Vegas, Nevada.
Identified as the shooter by NYPD and confirmed dead of an apparent self‑inflicted gunshot wound on the 33rd floor of 345 Park Avenue.
Firearms permit: Held a concealed carry permit issued in Nevada, and had an expired private investigator work card.
Vehicle & route: Drove cross-country from Las Vegas—through Colorado on July 26, Nebraska and Iowa on July 27, then into New Jersey around 4:24 p.m. on July 28—before arriving in NYC.
Believed to be a lone actor; no known ties to NYC or the building.
Mental health, note & possible motive
Tamura had a documented mental health history in Nevada, including two crisis holds in 2022 and 2024, but no major criminal record.
A three‑page note found on him referenced CTE (chronic traumatic encephalopathy)—a brain disease linked to repeated head trauma—and mentioned the NFL. The building he targeted houses the NFL headquarters.
Investigators continue to explore whether his perceived CTE and mental state motivated the attack, although no confirmed motive has been established.
How the attack unfolded
Shortly before 6:30 p.m. local time, surveillance video captured Tamura exiting a double‑parked black BMW on Park Avenue (between 51st & 52nd Streets), holding an M4 rifle.
He entered 345 Park Avenue, turned right, and immediately opened fire—killing an NYPD officer working security and several civilians in the lobby.
He shot a security guard and another person at the elevator banks, then took an elevator to the 33rd floor and killed a fourth victim before shooting himself in the chest.
At least one additional person was critically injured and remains hospitalized in critical condition; several others sustained minor injuries fleeing the scene.
Victims
Among the four people killed, one was NYPD Officer Didarul Islam, a 36‑year‑old immigrant from Bangladesh who had served for 3½ years. He was married with two young sons, and his wife is pregnant with their third child.
The other victims were two males and one female civilian. Their names have not been released pending family notification.
