Bankers and traders returned to work on a somber Tuesday morning in Midtown Manhattan, New York’s financial epicenter, one day after a shooting that killed four people, including a senior Blackstone (BX.N), opens new tab executive.

The Investment firm’s offices, however, were closed on Tuesday after it said Wesley LePatner, a senior Blackstone executive, was among those killed by a man who walked into the lobby of a Park Avenue office building where the company’s New York headquarters are located and opened fire on Monday.

“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,” the company said in a statement. Blackstone colleagues said they were shaken by the death of their colleague, who was called “brilliant, passionate, warm, generous, and deeply respected within our firm and beyond,” the statement said.

Near the end of the workday, a gunman whom police identified as Shane Tamura, 27, walked into the vast lobby of the building, which also houses the NFL headquarters, accounting firm KPMG, and real estate company Rudin Management, and opened fire. He killed four, including LePatner and a New York City police officer, and then went to the building’s 33rd floor where he killed himself, according to police.

“We are very saddened about the tragic loss of life … thankfully, everyone at (our) firm is safe,” said Mitchell S. Nussbaum, co-chair of law firm Loeb & Loeb, which has offices on the 18th to 22nd floors of the building. Nussbaum, who was not present during the incident, said staff are working from home and can do so for the rest of the week.

He said employees sheltered in place until police escorted them out last night. The final group of staff was escorted from the building sometime after 10 p.m. ET.

KPMG’s offices will also be closed on Tuesday, the company told Reuters.

Most financial firms’ offices throughout New York have security desks, with many restricting usage of elevators to those with security passes, but lobby access is less restricted. That may change in the aftermath of this incident.

A Goldman Sachs spokesperson told Reuters the company has “robust security protocols” throughout its buildings, and the firm is “constantly assessing their effectiveness to ensure they reflect best practices, especially based on recent events.”

Blackstone CEO Stephen Schwarzman and President Jon Gray wrote a note to staff on Monday calling the day the “worst day in the firm’s 40 year history,” according to sources who saw the memo. Later on Tuesday morning, Blackstone will hold a Zoom call, sources familiar with the matter told Reuters.

LePatner was a senior managing director at the firm, global head of core+ real estate, and CEO of Blackstone Real Estate Income Trust, the firm said. She joined Blackstone in 2014 from Goldman Sachs, according to the company’s website. She graduated from Yale and was married in 2006, according to a wedding announcement in the New York Times, and had two children, the firm said.

Several Blackstone employees barricaded themselves on a high floor by stacking up sofas, filing cabinets and other furniture after hearing loud noises, according to people who spoke with the employees.

Rudin Management, which owns the 634-foot (193 meter) building, did not immediately respond to a request for comment. The 44-story building, which occupies the entire city block between 51st and 52nd Streets and Lexington and Park Avenues, was completed in 1969. (Reuters)
