Shane Devon Tamura

Shane Devon Tamura was born in Hawaii and spent much of his childhood and adolescence in Santa Clarita, California. He later attended high school in the Los Angeles area, where he played football at both Golden Valley High School and Granada Hills Charter High School. Former teammates described him as sociable and generally well‑liked during his school years.

As an adult, Tamura relocated to Las Vegas, Nevada, where he worked in the security field. At the time of the shooting, he was employed in the surveillance department at Horseshoe Las Vegas, a casino property operated by Caesars Entertainment. He previously held a work card issued by the Nevada Private Investigators Licensing Board, though it did not authorize him to carry a firearm. His private investigator license had expired prior to the attack.

Public records and statements from law enforcement indicate that Tamura had a documented mental health history. Nevada authorities confirmed that he had been placed on psychiatric holds on two occasions, once in 2022 and again in 2024. Despite these incidents, he did not have a significant criminal record. In 2023, Tamura was detained on suspicion of trespassing at a casino property in Summerlin, Nevada, after refusing to leave while appearing agitated; the case was later dropped.

Tamura legally obtained a concealed carry permit in 2022. Investigators later confirmed that he possessed firearms, ammunition, and related equipment, and that he had recently traveled cross‑country by car in the days leading up to the shooting.

On the evening of July 28, 2025, a mass shooting occurred at 345 Park Avenue, a commercial skyscraper in New York City. The incident began at approximately 6:28 p.m. EDT.

Two days earlier, on July 26, Tamura left his home in Las Vegas and began driving east. Law enforcement tracking later confirmed sightings of his vehicle in Colorado on July 26, between Nebraska and Iowa on July 27, and in New Jersey on July 28 shortly before his arrival in Manhattan.

After parking his vehicle near the building, Tamura entered the lobby wearing body armor and carrying an AR‑15–style rifle. Inside the lobby, he shot and killed Didarul Islam, a 36‑year‑old New York City police officer who was off duty and working a paid security detail in full NYPD uniform. Tamura also shot and killed a woman who had taken cover behind a pillar and continued firing throughout the lobby area, striking additional victims.

Tamura then shot a security guard near the elevator bank. According to police officials, he allowed one woman inside an elevator to leave unharmed. He entered an elevator and traveled to the 33rd floor, which housed offices of Rudin Management. There, he shot and killed Julia Hyman, a 27‑year‑old employee.

After barricading himself on the 33rd floor, Tamura fatally shot himself in the chest. Emergency responders, including the New York City Police Department, Fire Department of New York, and the Federal Bureau of Investigation, secured the scene. Authorities later stated that Tamura acted alone.

Investigators believe Tamura intended to target offices of the National Football League, which are located on other floors of the building, but took the wrong elevator bank, leading him to a different floor.

The attack resulted in four fatalities and one critically injured survivor, an NFL employee who was shot in the back. Several others suffered minor injuries while fleeing the building. The shooting was described by officials as the deadliest mass shooting in New York City since the 2000 Wendy’s massacre in Queens.

After the shooting, investigators searched Tamura’s vehicle and recovered a Colt Python .357 Magnum revolver, ammunition, prescription medication including the antidepressant Zoloft, marijuana, headphones believed to be used during shooting practice, and two mobile phones.

A handwritten suicide note found on Tamura referenced chronic traumatic encephalopathy (CTE), a degenerative brain disease associated with repeated head trauma. The note mentioned former NFL player Terry Long, who died by suicide in 2005 after being diagnosed with CTE, and included statements expressing paranoia toward the NFL. A second note referencing CTE was also recovered.

In September 2025, the New York City medical examiner confirmed that Tamura had CTE.

Investigators also revealed that Tamura had recently purchased large quantities of ammunition and an aftermarket trigger. Authorities continued to examine the chain of firearm acquisition, including the sale of a vehicle and firearm components by an individual identified as Tamura’s supervisor.

Four people were killed:

• Didarul Islam, 36, NYPD officer working security detail
• Wesley LePatner, CEO of BREIT
• Julia Hyman, 27, Rudin Management employee
• Aland Etienne, 46, security guard

Officer Islam was shot in the back and died during emergency surgery. He was later posthumously promoted to Detective First Grade.

Following the shooting, citywide flags were lowered to half‑staff. A multi‑faith vigil was held at Bryant Park, attended by Mayor Eric Adams, Governor Kathy Hochul, Attorney General Letitia James, Police Commissioner Jessica Tisch, and hundreds of mourners.

Fundraisers for Officer Islam’s family raised more than $200,000. City officials and national leaders issued statements condemning the attack and offering condolences. Investigations into potential civil liability and security protocols at the building remain ongoing.
