The family of a Rudin Management employee killed in the mass shooting at the company’s office building last year is now suing the real estate firm.
The parents of slain Rudin associate Julia Hyman filed a wrongful death case against Rudin Tuesday in New York Supreme Court. Hyman was killed by a shooter who entered Rudin’s 345 Park Avenue on July 28, 2025. The suit additionally named McLane Security, which provided security services to the building, as a defendant.
The Hyman family alleges that the killing of their daughter was preventable and exposed Rudin’s “failure to provide and maintain effective security” at 345 Park.
“Julia’s death was not simply the result of a lone gunman’s actions,” attorneys for the Hyman family wrote in the complaint. “It was also the culmination of myriad security failures that allowed an armed assailant to move through a major office building in midtown Manhattan, shoot occupants, access an elevator, reach the 33rd floor, and kill a young woman.”
The new lawsuit is the second filed against Rudin related to the shooting. The widow of NYPD officer Didarul Islam, who was working off-duty as a security guard in the building when he was shot and killed, sued Rudin last December. That suit is ongoing and has progressed to discovery and depositions.
Rudin Management declined to comment. Additional defendant McLane Security did not immediately respond to a request for comment Tuesday.
Hyman was 27 years old and working as an associate at Rudin when she was killed. The shooter, who died by suicide in the building, entered the building with an assault rifle. 345 Park Avenue, bound by Park and Lexington avenues at East 51st and 52nd streets, is a 44-story office building that occupies a city block.
The shooter, 27-year-old Shane Tamura, drove from Las Vegas to Manhattan, entering the building with an assault rifle, according to police reporting. He fatally shot Detective Islam, building security guard Aland Etienne, Blackstone executive Wesley LePatner and Hyman.
“The unfathomable act of senseless violence that occurred one year ago at 345 Park Avenue was a tragedy of profound magnitude,” Rudin said in a statement for a story commemorating the one-year anniversary of the shooting. “The memories of the four innocent lives taken will live forever in our hearts. We extend our deepest love and compassion to each of their families, friends and colleagues.”
