A mass shooting erupted Monday evening, July 28, 2025, at an office tower in Midtown Manhattan, leaving at least four people dead, according to ABC News, including an off-duty NYPD officer and the gunman who took his own life. The attack took place at the 345 Park Avenue, home to major firms and organizations, prompting an emergency response and lockdown in the heart of New York City. ABC News posted a remarkable picture of office workers barricading themselves inside, using stacks of office furniture to block a doorway, while multiple outlets had footage of the alleged gunman striding into the building, holding a rifle in open daylight.
According to New York City police and witnesses, the violence began at approximately 6:30 p.m. ET, when Shane Tamura, reportedly armed with an AR-15–style rifle and wearing body armor, shot an off-duty police officer working security outside the main entrance of 345 Park Ave. He then stormed the building, opening fire in the lobby and upper floors and causing chaos among employees and visitors. Tamura continued his rampage up the skyscraper until authorities ultimately found him dead of a self-inflicted gunshot wound. The motive has not yet been disclosed.
