NEW YORK, NY — Julia Hyman, a 26-year-old Cornell University graduate and associate at Rudin Management, has been confirmed as one of the victims in Monday’s deadly mass shooting at 345 Park Avenue in Midtown Manhattan.

Hyman was killed in her office on the 33rd floor, tragically caught in the path of gunman Shane Tamura, who, according to investigators, mistakenly accessed the wrong elevator and ended up on the floor occupied by Rudin Management instead of his intended target—the National Football League’s headquarters.

Hyman’s death brings the total number of fatalities to four, including NYPD Officer Didarul Islam, 36; Blackstone senior managing director Wesley LePatner, 43; and security officer Aland Etienne.

The attack began shortly after 6:30 p.m., when Tamura entered the lobby of the high-rise and opened fire, striking the officer assigned to a corporate security detail and a woman attempting to flee.

He then moved toward the elevators, shooting Etienne at his security post before reaching the 33rd floor and fatally shooting Hyman.

The gunman, identified as 27-year-old Shane Tamura of Las Vegas, drove cross-country armed with an M4-style rifle, allegedly planning a targeted attack on the NFL due to grievances involving chronic traumatic encephalopathy (CTE), a degenerative brain condition linked to football-related head trauma.

Tamura left behind a handwritten note referencing CTE and former NFL player Terry Long.

Authorities believe he intended to confront the league over its handling of the condition but ended up on the wrong floor and killed employees of unrelated firms. Tamura ultimately turned the weapon on himself after the shooting spree.

In a statement, the Rudin family expressed deep sorrow over the tragic loss:

“The Rudin family and everyone at our company are devastated by yesterday’s senseless tragedy. Our thoughts and prayers are with those injured and lost last night, including our cherished Rudin colleague, a brave New York City police officer, a beloved lobby security guard, and an employee at a tenant firm.”

Blackstone, where victim Wesley LePatner served as Global Head of Core+ Real Estate and CEO of the Blackstone Real Estate Income Trust (BREIT), also closed its Manhattan offices in the wake of the tragedy.

“We are heartbroken to share that our colleague, Wesley LePatner, was among those who lost their lives in the tragic incident at 345 Park Avenue. Words cannot express the devastation we feel,” Blackstone said in a statement.

Labor union 32BJ SEIU identified Aland Etienne as a member and praised his service:

“Aland Etienne is a New York hero. We will remember him as such,” said union president Manny Pastreich, noting that the union is working with law enforcement and building management while offering counseling to affected members.

Meanwhile, the NFL confirmed that one of its employees was seriously injured in the attack but is in stable condition. In a memo to staff, Commissioner Roger Goodell emphasized that all other personnel were accounted for and safe.

Other firms with offices in the building, including KPMG, closed operations on Tuesday. In a statement, the accounting giant expressed gratitude to first responders:

“Our hearts are with the victims of this horrific act and their families, as well as all of our neighbors in 345 Park. This was a terrible, tragic, and frightening event.”

As the investigation continues, law enforcement officials are working to determine how Tamura gained access to the building and what security measures may have been bypassed. Mayor Eric Adams said preliminary findings show Tamura accessed the wrong elevator bank, leading him to Rudin Management’s offices instead of the NFL’s.

Police continue to comb through evidence and interview witnesses to piece together the full sequence of events behind one of the deadliest mass shootings in Manhattan in recent years.
