On Monday evening, July 28, 2025, a lone gunman identified as Shane Devon Tamura, a 27-year-old Las Vegas resident, carried out a deadly mass shooting inside a Midtown Manhattan office tower at 345 Park Avenue, killing four people, including an NYPD officer and a prominent Blackstone executive, before taking his own life. The attack, which unfolded around 6:28 p.m., sent shockwaves through the city, prompting a massive police response and raising questions about mental health and gun violence.
Surveillance footage captured Tamura exiting a double-parked black BMW with Nevada plates on Park Avenue between 51st and 52nd Streets, carrying an M4 assault-style rifle. Wearing body armor, he entered the 44-story skyscraper, which houses the headquarters of the National Football League (NFL), investment firm Blackstone, Rudin Management, and other major tenants like KPMG. Upon entering the lobby, Tamura immediately opened fire, fatally shooting NYPD Officer Didarul Islam, a 36-year-old Bangladeshi immigrant and three-and-a-half-year veteran of the force who was working a paid security detail. Islam, a father of two with a third child on the way, was hailed as a hero by Mayor Eric Adams and NYPD Commissioner Jessica Tisch for his bravery in the face of danger.
Tamura continued his rampage, shooting a woman who had taken cover behind a lobby pillar and a security guard stationed near the elevator bank. Another man in the lobby was critically wounded and remains in stable condition following surgery. Four others sustained minor injuries while fleeing the chaos. After sparing a woman who exited an elevator, Tamura proceeded to the 33rd floor, where he fatally shot Wesley LePatner, a senior managing director at Blackstone, Global Head of Core+ Real Estate, and CEO of Blackstone Real Estate Income Trust (BREIT). LePatner, a Yale graduate and Phi Beta Kappa member, was a respected figure in finance and philanthropy, serving on boards such as The Metropolitan Museum of Art and the UJA-Federation of New York. Blackstone issued a statement mourning her loss, describing her as “brilliant, passionate, warm, generous, and deeply respected.”
Investigators believe Tamura intended to target the NFL’s offices, located on the fifth floor, but mistakenly took an elevator to the 33rd floor, where Rudin Management’s offices are situated. A note found on Tamura’s body referenced chronic traumatic encephalopathy (CTE), a brain disease linked to head trauma, and expressed grievances against the NFL, suggesting he believed his mental health struggles were tied to his high school football days in California. Tamura, who had a documented history of mental health issues according to Las Vegas authorities, asked in the note that his brain be studied. A former standout running back at Granada Hills Charter High School in Los Angeles, he had also worked as a casino security guard in Nevada and held a valid concealed firearms permit issued in 2022.
Tamura’s journey to New York began days earlier, with his vehicle tracked through Colorado on July 26, Nebraska and Iowa on July 27, and Columbia, New Jersey, at 4:24 p.m. on July 28, just hours before the attack. Police searched his BMW, recovering a rifle case, a loaded revolver, multiple magazines, ammunition, a backpack, and prescription medication. The weapon, identified as a .223-caliber Palmetto State Armory M4-style rifle equipped with a scope, handguard, and shoulder sling, was smeared with blood, according to media reports.
NYPD Commissioner Jessica Tisch described the attack as a lone act, with no ongoing threat to the public. The building was secured within 90 minutes of the initial 911 calls, which flooded in as workers evacuated during rush hour. The investigation, led by the NYPD with support from the FBI and the Sparks Police Department, is focused on understanding Tamura’s motives, movements, and mental state. Mayor Adams called the shooting a “violent, despicable act” and emphasized the need for comprehensive mental health and gun safety reforms, noting the tragedy’s impact on a city that had seen record-low shootings in the first half of 2025.
The loss of Officer Didarul Islam, described as a “true blue” hero, and Wesley LePatner, a titan in real estate and philanthropy, has left a profound mark on New York. Flags across the city have been lowered to half-staff in honor of Islam, whose family mourns the loss of a devoted husband and father. LePatner’s death has reverberated through the financial and charitable communities, where her leadership and generosity were widely admired. As the investigation continues, authorities are piecing together the events leading to this horrific act, with updates expected as new details emerge.
