Shane Tamura, a 27-year-old man from Las Vegas, was identified as the shooter behind a deadly mass shooting in Manhattan on Monday night.
Shooter travels from Las Vegas to New York before opening fire
Tamura killed at least four people, including a New York police officer, before turning the weapon on himself inside an office building.
According to several reports, New York Police Commissioner Jessica Tisch explained that Tamura left Las Vegas on Saturday, 26 July 2025, and drove across multiple states.
His black BMW was found double-parked outside the Park Avenue building where the shooting happened. Inside the vehicle, police found a rifle case, revolver, ammunition, backpack, and medication prescribed to Tamura.
Tamura entered the building at around 18:28 EST (00:28 SAST), calmly walking in with a rifle. Police received several emergency calls at that time, reporting a man with a gun.
Commissioner Tisch said Tamura opened fire on an NYPD officer at the entrance, then shot a woman hiding behind a pillar. Inside the building lobby, he continued shooting, hitting a security guard behind a desk and injuring another person who was later able to give a statement from the hospital.
Tamura then went to the 33rd floor, which houses the offices of investment firm Blackstone.
He shot and killed another person before shooting himself in the chest. The bomb squad later confirmed there were no explosives in his vehicle.
Officer killed identified as father of two, with another on the way
The NYPD officer killed during the attack was identified as Didarul Islam, a 36-year-old father of two who had served in the force for over three years. His wife is currently pregnant with their third child.
Mayor Eric Adams described Islam as someone who died while saving lives. Commissioner Tisch called him a hero who made the “ultimate sacrifice.”
Tamura was once seen as a promising athlete during high school. His former classmate Caleb Clarke remembered him as energetic and full of potential, describing him as “the fastest kid” he had ever met. Clarke said Tamura was expected to do well in life, with dreams of making it in professional sports.
However, after high school, Tamura’s path changed. He worked at a casino in Las Vegas and seemed to fade from public view. Clarke said he was shocked by the news, noting that violence was not something anyone would have associated with Tamura.
Police confirmed Tamura had a documented history of mental health issues. Investigators are still trying to understand why he chose this specific location for the attack.
