A large-scale police response took place Monday evening at 345 Park Avenue in Midtown Manhattan following a deadly shooting by a gunman armed with an assault rifle.
The 44-story skyscraper houses numerous prominent offices and businesses, including Bank of America, J.P. Morgan, Blackstone, the National Football League, and various medical practices.
According to law enforcement sources, a man wearing a bulletproof vest calmly approached the building around 6:30 p.m. and opened fire with a high-powered rifle. Chilling surveillance footage showed the suspect walking across the entry plaza with the weapon at his side before the shooting began.
A police officer from the NYPD’s 47th Precinct — who was working a paid security detail for Rudin Properties, the building’s owner — was shot and killed at the scene. Three more were also struck by gunfire.
Authorities initiated a Level 3 Mobilization. The NYPD posted the following advisory on X: “Due to police activity, please avoid the vicinity of East 52 Street between Park Avenue and Lexington Avenue. Expect emergency vehicles & delays in the surrounding area.”
Witnesses described hearing “a barrage of shots,” with one person on the first floor saying it sounded like “an automatic weapon — like a high-capacity weapon.”
The gunman reportedly barricaded himself on the 33rd floor, where he was later found dead from a self-inflicted gunshot wound. Other victims were located on the same floor, sources said.
According to USA Today, the alleged gunman was identified as 27-year-old Shane Tamura, of Nevada. Police said the motive for the shooting remains under investigation and investigators are working to understand why the suspect targeted the commercial building.
