4 people died and multiple were injured in a mass shooting at an office building in Manhattan

A gunman opened fire inside a New York City office tower on Monday, July 28, killing four people before taking his own life in a shocking act of violence that rattled the heart of Manhattan.

The shooter, identified as 27-year-old Shane Tamura of Las Vegas, drove cross-country to carry out the attack. Armed with an M4 rifle, he entered 345 Park Avenue intending to target the NFL’s offices, but mistakenly took the wrong elevator and exited on the 33rd floor, according to authorities. He opened fire on that floor and in the lobby before turning the gun on himself.

Tamura, a former high school football player, claimed in a suicide note he suffered from chronic traumatic encephalopathy (CTE), the degenerative brain disease linked to repeated head trauma.

In total, four people were killed and several others injured, including one NFL employee. NFL Commissioner Roger Goodell denounced the attack as an “unspeakable act of violence” in a memo to staff.

Here’s what we know about the victims:

Didarul Islam, 36

An off-duty NYPD officer working a security shift in the lobby at the time of the attack, Officer Didarul Islam was among the first to confront the gunman. He was shot and killed while trying to protect others.

Islam, a 3½-year veteran of the NYPD, was a father of two, with a third child on the way. New York City Mayor Eric Adams praised him as a man of faith, courage, and character: “He loved this city. He died doing what he did best—protecting New Yorkers.”

Friends described Islam as a mentor in the Bangladeshi-American community and a role model for younger generations. Before joining the NYPD, he also worked in private security.

Wesley LePatner, 44

A senior executive at global investment firm Blackstone, Wesley LePatner was shot in the lobby of the building during the rampage. She served as CEO of Blackstone Real Estate Income Trust (BREIT) and was Global Head of Core+ Real Estate.

LePatner had worked at Blackstone since 2014, following a decade at Goldman Sachs. A Yale University graduate, she was remembered as a “brilliant, passionate, warm, generous, and deeply respected” leader by her colleagues.

“Wesley was a beloved member of the Blackstone family and will be sorely missed,” the firm said in a statement. “She embodied the best of Blackstone. Our prayers are with her husband, children, and family.”

Aland Etienne, 46

Also killed in the lobby was Aland Etienne, a longtime security guard. His death was confirmed by his union, 32BJ SEIU, which called him “a New York hero.”

“Every time a security officer puts on their uniform, they put their lives on the line,” said union president Manny Pastreich. “Their contributions are essential, though often overlooked.”

Etienne’s brother, Gathmand Etienne, shared his grief in a Facebook post, describing him as “more than a brother — he was a father, a son, and a light in our lives.”

Julia Hyman, 27

Tamura’s shooting spree continued on the 33rd floor, where he killed Julia Hyman before turning the gun on himself. Authorities believe Hyman was not a specific target but encountered Tamura when he entered the wrong floor.

Hyman was an associate at Rudin Management Company, which owns 345 Park Avenue. She had joined the company in November 2024, just nine months before the tragedy.

A recent graduate of Cornell University’s Peter and Stephanie Nolan School of Hotel Administration, Hyman was remembered by friends as smart, driven, and full of promise.
