The grieving family of a young real estate worker killed in last year's horrific Midtown mass shooting plans to sue the city for $65 million - claiming police utterly and completely failed to stop the crazed gunman before he stormed 345 Park Ave. The parents and sister of 27-year-old Cornell University graduate Julia Hyman said they were able to view never-before-seen security camera footage showing that NYPD Det. Didarul Islam - who was also slaughtered by the shooter - bears liability for her death, according to new court documents. The video, which captured the horrific events as they unfolded on July 28, 2025, allegedly shows the officer, who was working a paid security detail shift at the skyscraper, standing at the window in the lobby with a clear line of sight of the plaza and the gunman. 6 The parents and sister of 27-year-old Julia Hyman say the city may bear responsibility for her death. JuliaHyman/linkedin But Islam, a 36-year-old Bangladeshi immigrant, husband and father, allegedly utterly and completely failed to identify an obvious impending security threat and took no actions whatsoever to thwart or mitigate said threat, states the petition filed in Manhattan Supreme Court on Thursday. Gunman Shane Tamura, who had left his home in Las Vegas, Nevada two days earlier and drove to New York City in an apparent bid to target the NFL, exited his double-parked car and crossed an outdoor plaza outside the building while openly brandishing an M4-style rifle. He then entered a revolving door immediately to the right of Islam, who took no notice of the gunman, took no actions and offered no resistance whatsoever, the court papers allege. Not a single action by Detective Islam deterred, detected, disrupted, or delayed the gunman's unimpeded path from the street, up steps, across the plaza, and through the 345 Park Avenue lobby doors, the filing claims. 6 A crazed gunman killed four people at 345 Park Ave. during a horrific mass shooting on July 28, 2025 Bloomberg via Getty Images The actions and/or inactions of D #nypost #crimewatchnewyork
