Overview

• Shane Devon Tamura, a 27-year-old from Las Vegas with a documented mental health history, used an M4 assault-style rifle to kill four people and wound a fifth before dying by suicide in the Midtown skyscraper.
• One victim was Officer Didarul Islam, a 3½-year NYPD veteran working a paid security detail; three civilians were also killed and one remains in critical but stable condition.
• Police recovered a rifle case, a revolver, ammunition, magazines, a backpack and prescribed medication in Tamura’s double-parked vehicle, which traveled cross-country in the days before the attack.
• A handwritten suicide note referencing chronic traumatic encephalopathy and grievances against the NFL was found on the suspect, but officials have not confirmed a motive or why 345 Park Avenue was targeted.
• In Philadelphia, six shootings over the July 25–27 weekend left two people dead and at least eight injured, prompting city leaders to mobilize victim support services and review public-safety strategies.
