Didarul Islam, 36, a Bangladeshi-born man, was killed on July 28, 2025, after a gunman opened fire inside a Midtown Manhattan office tower at 345 Park Avenue. He was an NYPD officer assigned to the Bronx, and that evening he was working a paid security detail in uniform when the first shots tore through the building’s lobby during the rush of early evening.
In the first frantic moments, as people scattered behind pillars and toward exits, he was struck from behind and rushed to a hospital, where he later died as surgeons fought to save him.
Investigators said the attack unfolded quickly and with a kind of chilling purpose. The shooter arrived outside the tower, entered carrying a rifle and wearing body armor, and began firing in the lobby, cutting down victims at close range and spraying bullets across the space. Amid the chaos, the gunman moved deeper into the building, firing again near the elevator bank, then traveled upward to offices on an upper floor, where more people were shot. By the time the scene was secured, multiple civilians had been killed, others injured, and the building had become a sealed, echoing maze of locked doors, alarms, and sirens as officers searched floor by floor.
The suspect was identified by authorities as Shane Devon Tamura, 27, who had traveled cross-country to New York shortly before the shooting. Law enforcement recovered weapons and other items linked to him and examined a note indicating investigators were looking closely at his motives, including an apparent fixation on the National Football League and claims tied to brain injury from football. The case did not lead to an arrest because the gunman died at the scene from a self-inflicted gunshot wound after barricading himself on an upper floor, ending the attack in a murder-suicide.
In the days that followed, the city’s focus shifted from the locked-down tower to the human cost left behind. Islam was remembered publicly as someone who stepped into danger while others fled, a working cop taking a second job to provide for his family, and a man whose death reverberated through the neighborhoods where he lived and served. He left behind a wife who was pregnant at the time of the shooting and two young children, and he was later honored with a posthumous promotion as mourners gathered for services that portrayed his final moments as a last watch in the place he had sworn to protect.
