'Documented mental health history': Who was Shane Tamura? What we know about the Manhattan building shooter

• The suspected gunman behind the deadly Midtown Manhattan office shooting has been identified as Shane Devon Tamura, a 27-year-old originally from Hawaii who later moved to Las Vegas.
• Tamura opened fire at a high-rise office building on Park Avenue on Monday evening, killing four civilians and an NYPD officer before turning the weapon on himself.
• Authorities told the Associated Press that, Tamura had a documented history of mental health issues, though his exact motive remains unclear.
• “We are working to understand why he targeted this particular location,” said NYPD Commissioner Jessica Tisch during a press briefing.
• A concealed carry permit issued in Las Vegas in July 2022, bearing Tamura’s photo, was found at the scene.
• Surveillance footage showed him exiting a black BMW, armed with a .223-caliber Palmetto State Armory AR-15-style rifle equipped with a black scope, handguard, and shoulder sling.
• The gun, priced around $420, was reportedly the same one used during the attack, New York Post reported.
• Police said that Tamura first shot an officer stationed at the building's entrance, then opened fire on a woman trying to flee, followed by a security guard and another man inside the lobby.
• He later shot himself at the scene. Police later found a revolver, ammunition, and extra magazines in his vehicle.
• While an official biography is yet to be confirmed, unverified reports suggest Tamura was a former high school football player, having played as a running back at Granada Hills High School in California.
• A former teammate, Caleb Clarke, described him as “a goofball” and “class clown,” full of energy, according to NBC.
• The shooting took place at 345 Park Avenue, a prominent high-rise that houses major institutions including Blackstone, the National Football League, and the Irish Consulate.
• According to NYPD Commissioner Jessica Tisch, Tamura immediately opened fire at the entrance, shooting a uniformed officer before turning the weapon on others inside.
• A woman who tried to flee was gunned down, followed by a security guard behind a desk and another man in the lobby.
• Emergency crews responded swiftly to the scene, where four civilians were found dead and a fifth was rushed to the hospital in critical condition.
• The slain officer was pronounced dead at the hospital. Authorities have not released the names of the victims, and the investigation is ongoing.
• Investigators are still piecing together the full timeline and motivation behind the attack.
