NEW YORK (Reuters) -An investment banker at Bank of America has died, according to social media posts from the family and the bank on Tuesday.

The deceased was identified as Leo Lukenas III by his twin brother Les Lukenas whose LinkedIn page contained a post about the death. The post connected to his brother's Linkedin page which showed he was an investment banking associate at Bank of America.

Lukenas's age was not available from the bank or the medical examiner but his brother said they had been "together for 35 years." According to his LinkedIn profile, Lukenas graduated in 2010 from Sonma State University in California and then spent a decade in Army Special Operations, a member of the U.S. Green Beret special forces, before joining Bank of America in 2023.

"Tragically, Leo passed away on May 2, 2024, leaving behind his wife and two children," according to a message on a fundraising website, which carried a photo of the army veteran and his family.

Les Lukenas asked people to donate to Leo's family on the website. "I am grateful for the 35 years we spent together, side by side, from playing junior golf to earning our Green Berets," he wrote.

When asked about the cause of death, the New York Office of the Chief Medical Examiner cited "acute coronary artery thrombus". The disease causes the formation of a blood clot inside a blood vessel of the heart.

Reuters could not immediately reach Lukenas for further comment.

Lukenas was part of Bank of America's financial institutions group (FIG) team that advises bank clients on deals, according to his LinkedIn page.

Investment bankers are typically key fee generators for Wall Street banks. Global banking, which also houses Bank of America's investment bank, accounted for around 30% of the bank's income in the first quarter.

The death has shaken some colleagues and ex bank colleagues, said two sources familiar with the matter.

Bank of America said "our focus is on doing whatever we can to support the family and our team, who is devastated."

The bank is also paying for any staff to attend the late banker's funeral, it said.
